There are two main kinds of dictionary: standard and learner's. The standard dictionary is made mainly for native speakers, where readers are expected to be fluent in the language. The learner's, as we expected, is mainly made for foreign learners, and its definition of each word is simpler and restricted to core vocabulary.
For example, let's take a look at the word ostentatious in Merriam - Webster Dictionary:
- Simple definition: displaying wealth, knowledge, etc., in a way that is meant to attract attention, admiration, or envy
- Full definition: marked by or fond of conspicuous or vainglorious and sometimes pretentious display
My (English) vocabulary is wide enough to understand most contexts, yet I still find it's hard to fully understand the full definition of the word, though I can guess its meaning. Even if I spend time to look up conspicuous or vainglorious to really understand their meanings, I still have the feeling that I won't reach the satisfaction of understanding the word from reading the simple definition.
Question: What advantages do standard dictionaries have over learners' dictionaries? I think the only possible thing is the trade-off of correctness in the simple definition; but even so, a simple definition should define the word correctly because it is still a definition.
