ser and estar- both mean to be
Words with multiple meanings in spanish are called (PALABRAS POLISEMICAS).
Ser and Estar are verbs and you can't use them in the same context. I think you are looking for words that have different meanings not the same ones. For example, Banco, Banco and Banco are spelled the same but have 3 different meanings.
Banco: Bank, where you keep money.
Banco: A bench, to sit.
Banco: Banco de peces; a fish tank.
The majority of words in Spanish have more than one use or meaning. This is the same as in English.
Synonyms are two or more words that have the same or similar meanings.

Answer: While Spanish has more total speakers, French has a wider distribution of speakers around the globe and is spoken on every continent. French is easier to learn than Spanish; the latter has more irregular verbs, four words that mean 'you', two words that mean 'for', etc. French also sounds nicer.

This doesn't make any grammatical sense in spanish, so I think you're missing some words, but it means "how are you" and "no more pants".
