Ser is the eighth most used word in the Spanish language.
I must admit I approach this word with some trepidation. This monosyllabic verb, for yes, ser is a verb, is the bane of the lives of all learners of Spanish.
Ser means “to be”. Said, or written like that, it seems quite easy. However, there is another verb meaning “to be”, that is estar. And this is where the fun (or problems) start. Moreover, the problems arise, obviously, because of the frequency with which this verb (these verbs in Spanish) occur.
However, we need to bash on in the interests of brevity.
To add to the mix, el ser (a noun) means being.

Es muy alto – he is very tall
