How do you say sile in Gaelic?

There isn't a single perfect translation for "silence" in Gaelic, as the best word depends on the context and the specific nuance you want to convey. Here are a few options, with slight differences in meaning:

* Scottish Gaelic: `sàmhchair` (pronounced roughly sah-vhar) is a common and generally good translation for "silence."

* Irish Gaelic: `tosach` (pronounced roughly tosh-ach) means "silence" or "stillness," often implying a quiet beginning or a peaceful state. `samhradh` (sah-vrah) means summer, but can be poetically used to refer to a quiet or peaceful time.

The best choice will depend on the sentence. For a simple request for silence, `sàmhchair` (Scottish Gaelic) or `tosach` (Irish Gaelic) would likely be suitable.
