Depending on how it is used, “silly” can be an adjective and a noun.

The word “silly” comes from Old English. From Old English sælig, "lucky, blessed" — the meaning drifted over centuries from "blessed" to "innocent" to "simple" and finally to today's "foolish," a similar journey to the word "daft.".

“Silly” is a fairly common word in modern English, usually learned at around the A2 level.

Silly describes behaviour that is foolish or lacking good sense in a light, often laughable way, and it is frequently affectionate. Stupid is a harsher word that criticises someone's intelligence and is far more likely to offend. A silly joke invites laughter; calling someone stupid is an insult.

Usually not a serious one. Silly is one of the gentlest words for foolish, and the noun use, as in "you silly," is often affectionate, especially with children or close friends. Context and tone matter, though: in a formal setting or an argument, calling an idea silly is dismissive.

Both describe a lack of good sense, but foolish is the more serious criticism, suggesting poor judgment with real consequences, as in a foolish investment. Silly is lighter and often implies harmless, laughter-inviting behaviour, like a silly dance. You can be silly on purpose for fun, but people are rarely foolish on purpose.
