Just to confirm, Dámelo
is not a contraction and actually it is a grammatical structure that works as an order or like in the case of Me lo dá?
as a polite request.
The tone changes since the way you request is different and probably you will choose one of them depending on who you are addressing (Dámelo
is informal and direct, me lo dá?
is formal and polite). You may find this review of Spanish grammatical structures useful.
On the other hand, contractions are shortened versions of the written and spoken forms of a word or a group of words, and are created by omitting internal letters. The typical examples are:
A + el = al
De + el = del
There are other examples which are not so common(as far as I know) in Latin America such as:
Donde + quiera = doquier
De + esto = desto
I hope this helps!
del
,al
, etc. the example that you gave is a gramatical construction that allows pronouns to be added onto the end of the verb. Ex: infinitive verbs, positivetu
commands, and positivevosotros
commands.
