Essential Vocab for Language Learning

This is a personalised list originally based on 625 common words

Discarded words such as "newspaper" and "cake" since they're not important to my life and probably won't come up often (or if someone is asking about them, I'm probably not that interested anyway).
Discarded American-centric words (inch, foot, pound). Added important words that were missing (i.e. near, far, next, previous).
Added extra food words.

adjective
