Learners often assume that vocabulary means a list of words with their translations. It is a reasonable assumption and it is the reason many lists are learned and then fail to arrive when needed.
A word in use is not one piece of information. It is several. You need its meaning, but you also need to know which words it sits beside — you make a decision but take a photograph, and no rule explains why. You need its register: 'kids' and 'children' mean the same thing and belong in different sentences. You need its grammar: 'suggest' is followed by one structure and 'advise' by another. And you need to be able to recall it quickly enough to use mid-sentence, which is a different skill from recognising it on a page.
This is why recognising a word and being able to use it are separated by a surprising amount of work. Most learners' passive vocabulary — words understood when read — is several times larger than their active one. The gap is not a failure. It is normal, and it closes only through use.
The practical consequence is about how you record a new word. A list of word and translation gives you one of the five things. A short sentence you wrote yourself, containing the word in a situation you might plausibly be in, gives you several at once and attaches the word to a memory rather than to a line on a page.
It is slower per word and it is the reason the words come back when you need them.
