The phrase 'ไม่กี่ (mâi gìi)' is used in Thai language to indicate a small number or quantity, which can be understood as 'not many' or 'a few' in English. It is usually used in front of a noun to limit its quantity. The particularity of 'ไม่กี่ (mâi gìi)' is that it is used to refer to a limited specific quantity that is considered to be small relative to the speaker's subjective perception, rather than being an objective small amount.
