Learning a Foreign Language with ADHD: Words, Review, Speaking

A new language comes to the ADHD mind with two different faces.

One face is very attractive: new sounds, new words, the thrill of understanding a scene of a series without subtitles for the first time. Novelty, play, small rewards that arrive immediately.

The other face is long and repetitive: seeing the same word for the twentieth time, irregular verb tables, a middle period that lasts months in which progress is almost invisible.

When I look at my own learning pattern, I see someone who is very good at the first face and struggles a great deal with the second. I can sink for hours into a subject that interests me; I cannot hold a list that does not interest me in my head for three days. Learning a language seats these two at the same table.

First an honest note: there is little research

There is a lot of content on ADHD and foreign languages, but most of it is shared experience or teacher advice. Because the number of controlled studies is small, I want to say from the start that some of what I write here is inference rather than evidence.

One of the most cited studies belongs to Sparks and colleagues. They compared university students registered with ADHD, a learning disability, or both; some had completed the foreign language requirement by taking the courses, and some had applied for an exemption. On the test measures there was very little difference between the groups; all five groups scored average or above average on measures of cognitive ability and academic achievement. Diagnostic classification and exemption application did not explain differences in aptitude or performance between the groups (Sparks et al., 2005).

What I take from this finding is this: behind the sentence "I have ADHD, I cannot learn a language" there is no strong evidence.

A more recent study asked 226 adults with ADHD, native speakers of Polish who knew more than one language, about their language-learning experiences. The participants' overall view of their experience of learning and using additional languages was neutral. There were signs that the hyperactive/impulsive presentation might affect additional language learning positively; co-occurring autism or dyslexia, on the other hand, showed no clear effect on language knowledge in this group (Kałdonek-Crnjaković, 2026). The study rests on a survey and on beliefs and self-report; so I read it as a sign of direction.

The loop that holds a word in mind

The place where language learning meets ADHD most directly is, I think, new words.

Baddeley and colleagues, reviewing vocabulary-learning studies in adults, children and different clinical groups, proposed that the phonological loop plays a key role in learning the sound form of new words. In their view the main function of this loop is to hold unfamiliar sound patterns temporarily while a permanent memory record is forming (Baddeley et al., 1998).

The phonological loop is a part of working memory. A meta-analysis looking at the relationship between working memory and a second language found, in the data of 79 samples and 3,707 participants, that working memory was positively related both to second language processing and to second language proficiency; the estimated effect size was 0.255 (Linck et al., 2014). This is a meaningful relationship but not one that decides things by itself. Working memory does not explain the whole of language learning.

I described the everyday side of working memory in ADHD in the article working memory and forgetfulness. The inference I carry over to language is this: trying to make a new word permanent in a single go can be especially tiring in ADHD. Short and frequent encounters carry the word to long-term memory with less load.

A word does not settle after being heard once; it settles after being met a few times, at intervals.

Which part may feel easy and which part hard

This section is a picture I put together from my own observation and from what people with ADHD often describe. It should not be read as a classification confirmed by research.

The side that may get easier: jumping into speaking. Impulsivity can push the fear of making mistakes back a little. The positive sign seen for the hyperactive/impulsive presentation in the study above is consistent with this observation.

The side that may get harder: grammar tables, spelling, long-term review and the boring middle period. And, while listening to someone who speaks fast, holding the beginning of the sentence in mind.

Between the two: interest. If there is a series, a game or a subject I am interested in, I can consume content in that language for hours. This is the power of learning through hyperfocus. But when the interest fades and there is no system to take its place, the language goes off to join the half-finished pursuits waiting in the closet.

There is a shame side too. As an adult, speaking like a child in a language, making mistakes, ending up in a ridiculous position with the wrong word... For someone sensitive to criticism, this can weigh heavier than grammar. That is why I care about doing my first speaking practice in an environment where I know I will not be judged.

Listening and speaking

One of the things that tires me most when learning a language is listening. I cannot set the speaker's speed; while I hold the beginning of the sentence, the middle goes by. This is the form, in another language, of the half-sentence problem I have when taking notes.

There are two settings that can work here. The first is subtitles. Listening and reading at the same time lets the eye catch the place the ear missed; watching first with subtitles in the native language, then with subtitles in the language I am learning, can be a step toward watching without subtitles. The second is speed. Many listening apps allow you to slow the content down. Slowing down feels boring at first, but being able to keep the connection to the end of the sentence leaves more behind than a fast, uncomprehended listening.

In speaking, the problem runs the other way: sometimes I jump ahead too fast. Impulsivity gives courage, but the same courage can lead me to move on to another sentence without finishing one, and to continue without correcting the half-finished structures. Noting down two or three mistakes that stay in mind after a speaking practice leaves a small goal for the next practice.

Making progress visible

The hardest period of learning a language is the middle, because progress is not visible. In the first weeks you learn a new word, a new pattern every day, and the difference is clear. After a few months the same effort seems no longer to produce a visible difference. In ADHD, the value of a reward that stands far away falls quickly; in the glossary, reward delay.

What is meaningful for me in this period is making progress visible myself. Reading the same short text out loud every few weeks and recording myself, or rewatching a video I did not understand in the first month. When I hear the difference with my own ears, the distant reward comes a little closer.

A routine I find worth trying

A small unit a day. A one-hour study plan usually does not see the second week in ADHD. A ten-minute vocabulary review and a short listening session can be done every day.

Saying the word out loud. Saying the answer aloud before turning the card gives the phonological loop direct work and ties my attention to the card.

Learning the word with a sentence. A word list on its own is boring and disconnected. A word standing inside a sentence that interests me comes back more easily.

Leaving the timing of review to a system. If I try to remember when to review what, I forget. A flashcard app that does spaced repetition takes this job from me. Why spaced repetition works and where it snags in ADHD I wrote about separately in the article memorization and spaced repetition.

Returning to the same content. Finding new content is exciting; but looking for a new series, a new channel every time can also turn into a way of stalling. Listening to an episode or a song I like a few times lets me hear a little more each time. Because I already know the story, my attention stays on the words. Familiar content is also not lost in the moments when the mind drifts; I catch the part I missed the next time I listen.

An appointment from outside. A fixed weekly speaking lesson or a language partner is what brings me to the table in the weeks when inner motivation drops.

Changing apps does not count as progress Discovering a new language app gives you a feeling of progress, like buying a new notebook. But with every switch your streak counter, your word deck and your habit are reset. Using one app for a few months without quitting gains far more words than trying a new one every month. The general form of this cycle is in the article app hunting.

Sometimes a person wants to "finish" a language, yet a language is not something that gets finished. The question that is meaningful for me is less "how much have I learned" and more "how many times did I meet that language this week." The answer to the second, over time, changes the first by itself.
