Su is the fourteenth most common word in the Spanish language, and, as such, it really is a “no-brainer” (an expression I have heard in the past some of my students say) – you have to know it because it crops up so often.
Su is a possessive adjective.
The dictionary definition of su is:-
its (not it’s.. but that is an English grammatical can of worms, which I will not open!)
A long, and potentially very confusing list of words there. Of course, the specific meaning all depends on the context, that is to say the words and meanings surrounding the word su.
In the spirit of these podcasts, I will Keep It Simple. The most frequent meaning is his or her.
Here are some examples:-
Juan tiene su camisa – Juan has his shirt
Juanita tiene su camisa – Juanita has her shirt
“¡Tenga, su camisa, señor!” – “Here you are, your shirt, sir!”
el perro y su cachorro – the dog and its puppy
Juan y Juanita tienen su casa cerca de la playa – Juan and Juanita have their house near the beach.
Well su, for its diminutive size, certainly packs a punch!
So, there we have it – su is the 14th most common word in the Spanish language. It is a “no brainer” for the Spanish language learner, you simply have to know it!
