“Crude” is an adjective.

The word “crude” comes from Latin. From Latin crūdus ("raw, uncooked"), the same root as "raw" itself.

“Crude” is a fairly common word in modern English, usually learned at around the C1 level.

Crude describes something raw, roughly made, or vulgar in style, while rude primarily means impolite or disrespectful towards people. A crude joke is coarse or tasteless; a rude remark is bad-mannered. The words overlap when describing vulgar behaviour, but rude centres on lack of courtesy.

Because crude means in a raw, natural, unrefined state. Crude oil is petroleum as it comes out of the ground, before it is processed into fuels and other products, and in the oil industry the noun "crude" on its own is standard shorthand for it.

Both can describe offensive language or humour, but vulgar focuses on indecency or bad taste, while crude also suggests something rough, unpolished, and lacking tact. Crude has additional neutral senses that vulgar does not share — a crude sketch is simply rough, and crude oil is simply unrefined.

It depends on the sense. Describing a tool, model, or estimate as crude just means it is rough, simple, or unsophisticated, with no moral judgement. Calling a person's language or humour crude, however, criticises it as vulgar and lacking tact.
