can 'esta rather than 'es' be used in this case
This sentence is weird, but you must use "es" in this case.
MAkes sense for "la mujer." How about "Ella esta una mujer cansado"? She is a tired woman? She is one tired woman!
Seems to me that in this case, cansada refers to a permanent trait/charasteristic of la mujer, rather than a temporal emotional state. Therefore it's es, not esta.
Why do I have to put candasa after the noun? Is 'la cansada mujer' also correct?
