Assay is a word that is spelled with two S's, not one. The first S is pronounced as a regular S sound with the IPA symbol /s/. The second S, however, is pronounced more like a Z sound with the IPA symbol /z/. This is because in English, the pronunciation of certain words can be affected by their context and neighboring sounds. To correctly pronounce assay, then, remember to use the /s/ sound for the first S, and the /z/ sound for the second.

The word "assay" originated from the Old French term "assaier" which came from the Latin word "exagium". "Exagium" means "weighing" or "weighing out", and it is derived from the verb "exigere" meaning "to examine" or "to test". The word eventually evolved in Middle English to "assay" with the meaning of "trial" or "attempt", and it was primarily used in the context of testing the purity and quality of metals and coins.
