The term of synalèphe (of the Greek συναλοιφή/ sunaloiphế , “fusion, union”) described the fact that two Voyelle S in Hiatus are marked in only one Syllabe. It is thus a Métaplasme.

This technical term, that one still meets in the Métrique (gréco-Roman, Spanish, Italian), remains very vague: indeed, he does not say if the two vowels form then a Diphtongue by Coalescence (when it is possible), if one of them is amuïe (elision, for example), if one obtains a Crase, a Contraction, a fart, a Synérèse, etc
