I have a nerdish love of verbs. For me, it’s where it all comes together in language. They are sentence glue. Conjugate them, and you can hang the rest of the sentence from them like on the branches of a tree. But there is a small group of verbs that always make me feel more expressive and fluent in a foreign language. They are the modal verbs.

You have likely already come across them in your studies. In English, they are words like can, must, should and so on. They are often irregular, and very high-frequency in the languages they belong to.

So why are they such a boost to fluency?

À la modal verbs

The magic of modals is that they nuance what you say. They decorate your sentence tree with colourful subtexts. Technically speaking, they layer your speech with modality – the ability to express situations which may not be real.

Concretely, modals are verbs that imply intention, possibility, obligation and probability. These are all complex nuances, but very quick and easy to apply succinctly with modals. And they fix a common frustration of beginners: boring conversation syndrome.

It is a common beginner language learner experience to feel limited by straightforward, indicative tenses. You quickly frustrate yourself in speaking if all you can do is make statements of fact. I am a student, I went to a concert, we have a dog, we travelled to Spain. Hmm – boring!

Modal verbs change that up. They colour the story. Suddenly, I could be a student, I wanted to go to a concert, we should have a dog, we might go to Spain. Beyond bare statements of fact, you are now expressing hopes, wishes, dreams, judgements, assessments and more. From dull zero to language learning hero through the addition of just a few words.

Letting you off lightly

Modal verbs can actually make your language easier to speak, as well. Since they usually connect to the bare infinitive – or most basic form – of another verb, they give you a wee respite from conjugating it.

For example, let’s take the Spanish verb phrase:

ir al colegio (to go to school)

Ir is a notoriously irregular verb. If you are fumbling for its past form when trying to say I went to school, then there is a simpler way: modal verbs and constructions. If you have memorised the simple past of ‘had to’ in Spanish, it becomes easy:

tuve que ir al colegio (I had to go to school)

That tuve que construction just saved you if you had forgotten the form fui (I went). Fair enough, the meaning is subtly different – you are expressing obligation here instead. But it is close enough to express the original indicative sense that you went to school too. A neat trick.

The great thing with this tactic is that just learning a couple of conjugated forms of modal verbs can go a long way. You need only learn a few key forms at first. Perhaps the first person present and past forms (I must, I had to, I can, I could and so on) are the most immediately useful for conversation. Then, simply clip on whole verb phrases to the end – no conjugation required. An instance fluency boost!

To continue the metaphor of the verb as the trunk of a tree, modal verbs are big, sturdy branches that can comfortably take the weight of even more verbs.

More bang for your buck

Let’s face it – some words are more useful than others.

For a start, modal verbs are common, high-frequency words that you will regularly come across. A good benchmark is where a word appears on a frequency list of words in the target language. Anything in the top hundred suggests that you will be exposed to the word all the time. Spanish puede (can) features in its top sixty, as does its French counterpart peut and German kann.

But something makes them even more useful that just being frequent. They are often semantically overloaded, too, meaning that they have multiple meanings depending on context.

Just take must in English. It can be a bare indicator of obligation, as in we must go. But it can also express the speaker’s assessment of high probability, as in they must be the new students. Many languages mirror this usage, such as the Spanish debe de estar cansado (he must be tired).

Consulting any good reference on your target language should throw up scores of examples. This Wiktionary page on the Spanish deber (must) gives a good overview of that word, for instance. After checking out constructions there, you can then hunt down sample sentences containing them on a service like Tatoeba.

Overloaded words are excellent news for squeezing lots of language out of a little learning. You get even greater mileage than normal out of each modal verb mastered.

Modal Verbs : fast-tracking fluency

Convinced by these little nuancing fluency helpers? The facts speak for themselves. Modal verbs are high frequency words. There are just a few to learn. They have dense, multiple meanings. And they make speaking easier when you are still grappling with general verb conjugation. They are the perfect fodder for a bit of language hacking towards fast fluency.

Could it be magic? It just might. Say yes we can and enjoy pumping up your fluency with modal verbs!
