All languages existed long before anyone wrote down the grammar. -Steve
This is the reason why I don’t heavily focus on grammar. I consider grammar as merely theories about the language, whose rules are often wrong, unless you add a huge amounts of exceptions to these rules. All these exceptions to the rules make it overly complex and complicated and thus quite overwhelming, especially when you aren’t very familiar with the language. As you get more advanced, it is useful to draw your attention to various patterns, but as Steve mentioned, you have to think about opportunity costs. Ten hours going through a grammar book (or using Anki or whatever) means ten hours less of reading/listening.
Every time you look at the same information, the same example or the same rule, the brain is working less and less hard… You’re far better off encountering examples of usage patterns in a variety of different contexts, in different books, in different audiobooks, in different podcasts, in different texts. You’ve gotta spread that around. You can’t just focus on a limited number of rules and examples and expect that that is going to create the necessary language competence. -Steve
You need to get used to the word being used in all the different grammatical contexts, as, at the end of the day, I consider language learning to be mainly a rote learning activity on a large scale, if your goal is to be native-like fluent. Thousands upon thousands of sentences and collocations need to be rote learnt to be able to hear, read, and speak and convert to/from meaning at native-level speed. No amount of (semi-wrong without a kajillion exceptions) theories can truly prepare you to subconsciously understand and speak meaning at such a speed.
(Furthermore, a variety of contexts is a great way to ‘naturally’ learn vocabulary in order of frequency, as you end up encountering the most frequent words first, and thus learning them in such an order.)
The only issue with studying a variety of content on LingQ is that encountering New Words on LingQ takes significantly more time than repeating the same content, because of all the clicks required to get a good translation of the word (a minimum of two clicks, but often more).
you could definitely increase your wpm if you reprocess the same material a second time with LingQ. Because in this scenario, you don’t have to stop looking up blue words, and you can focus only on converting yellow words. @davideroccato
Is extensive or intensive reading faster for vocabulary acquisition? - #75 by davideroccato
Depending on the amount of New Words in a text and a few other factors, but you are looking at probably 1.5x to 4x more words per minute re-studying content than studying new content with New Words.
So you are really juggling the importance of a variety of content with trying to reduce the amount of time-waste LingQ adds to studying new context.
