Etymology: Densimeters are the plural of "densimeter", a compound built from the English adjective "dense" and the element "meter", which descends from the Greek "métron", meaning "measure". The linking "-i-" is a connecting vowel, a device borrowed from Latin-style word formation that lets classical-style stems join smoothly. So the plural simply names more than one instrument for measuring density. The core of the word is therefore a fusion of English and Greek parts. "Dense" came into English from Latin "densus", meaning thick or crowded, while "meter" passed into English through French "-mètre" from the Greek root. Both halves were combined in English, which is why the word looks like an everyday English adjective fused with a scientific suffix.
