This is the 227th most frequent Romanian word.
s
In Romanian, "s" is not a standalone word but a letter of the alphabet. It could also be a contraction (e.g., "să" or "sunt") depending on the context.
The 's-' denotes a reflexive pronoun usage, indicating the subject is also the object of the action (woke up herself).
Ea s-a trezit devreme astăzi.
She woke up early today.
The 's-' works as part of a conditional reflexive verb construction, implying a potential or hypothetical action involving the subject.
El s-ar putea duce la petrecere.
He might go to the party.
The 's-' in connection with 'ăscultăm' illustrates pronoun-verb agreement for the action being reciprocal or mutual usage.
