Learn English – Word to describe something difficult to remember

single-word-requests

This would be used when someone has to memorize certain information, but the nature of that information is difficult to grasp and recollect or a large set of numbers. Is there a particular word for these?

Best Answer

The question is somewhat broadly focused on both memory and comprehension. Addressing "difficult to grasp or recollect" as in the first example, a thing that is difficult to remember in that way can be referred to as "elusive".

Referring then to "a large set of numbers", as in the second example, a word for difficult to remember due to size or volume (i.e. a large list or long passage of text) is a "challenge". It can be a "challenge to remember", a "memory challenge", or simply "challenging".
