Synonym and Homonym for Listening

A synonym is a word or phrase that means exactly or nearly the same as another word or phrase in the same language. Words that are synonyms are said to be synonymous, and the state of being a synonym is called synonymy.

For example, the word begin, start, commence, initiate are all synonims of one another.

In linguistics, homonyms, broadly defined, are words which are homographs (words that share the same spelling, regardless of pronunciation) or homophones (words that share the same pronunciation, regardless of spelling), or both. 

For example, according to this definition, the words row (propel with oars), row (argument) and row (a linear arrangement) are homonyms, as are the words read (peruse) and reed (waterside plant).

What the connection between synonim and homonym in listening intermediate material? For some student I think it can be their dificulty because all of these words has a same form even same pronoun.

How to resolve this problem, because so many words sound exactly same? So I give two ways here, first we can use another word that has a same meaning, and second is you should know about the content that talked about, what sentence said, what sentence mean, and you should listen carefully.
