I use Anki to study French. Vocabulary works fine but the main difficulty with French as a second language is the conjugation of verbs. There are least five conjugations
présent
imparfait
futur simple
conditionnel
imperatif
you need to know even if you aren’t that advanced (if you want to study “high brow” French literature there are 2-3 more you need to know, that are only used in written language)
(You also need to know passé composé but that is simple)
For regular verbs, all these have six different suffixes.
The good thing is that these forms are quite regular. You just have to combine the correct stem and correct suffix, and the stems and suffixes are reused. The bad thing is that it is easy to mix up these combinations. For example, parler (talk or speak) (I will only use the first person as example, if you want to look into the details, look here)
présent - je parle
imparfait - je parlais
futur simple - je parlerai (this suffix is actually the présent of avoir!)
conditionnel - je parlerais
imperatif - n/a
For the first two, the stem is parl and for the second two it is parler. You can also see that imparfait and conditionnel use the same suffix but different stems (I know that they think the stem is parl in all cases and that er is part of the suffix but well, it isn’t
Furthermore, very common verbs like avoir (have), aller (walk) and être (be) stems are completely irregular:
avoir - aller - être
présent - (no stem at all) - (no stem) - (no stem)
imparfait - av - all - ét
futur simple - aur - ir (!) - ser (!)
conditionnel - aur - ir (!) - ser (!)
imperatif - (no stem) - (no stem) - so (!)
Basically, there are a LARGE number of combinations, but a lot of them are regular but there are also a lot of irregularities. You would save a lot of brain power if you could learn these combinations and irregular stems, but I can’t! Thanks to Anki I have increased my vocabulary with maybe 8000-10 000 words (and only have some 30 repetitions/day) but I suck at these verbs.
I have tried different types of Anki notes for this, e.g., “which use the same stem?” or “which use the same suffix?”, “what is the imparfait stem for être?”, “conditionnel of aller, 2nd person plural (you)?”, “list all six imparfait conjugations for être?” etc but as soon as the interval starts to become an month or so I forget the answers and have to start from zero again.
How do you use flashcards to study this type of grammar?
