Slew is a homograph. It can have wi dely different meanings with the same spelling. 

Billy Bob slew a slew of snakes by the slew.

A homograph can also be pronounced a different way, so if I was teaching using your example I'd call it a homonym since they are pronounced exactly the same way but have different meanings. Isn't the English language grand? Teaching the /u_e/ /oo/ /ew/ /ou/ /ui/ sound spelling rules can be super confusing for students (and teachers if they aren't given a specific phonics course to follow).

I had a slew of cats too. They all had radically different personalities.

Imagine what a non-native speaker, accustomed to Spanish where we know how everything's pronounced on sight,goes through. To this day, I struggle.

Funniest faux pas ever? English Honors in eleventh grade. Mr Rupple's showing a film, and I read the first word on screen out loud. Problem was I pronounced FOCUS as fuck us.  Cue universal laughter.

The poor guy I met named Fuqua in college  probably never forgot my admittedly intentional mispronunciation of his name.

The common one was in our Spanish class and asking how old you are (años) and not pronouncing the tilde (~).  Though, on a gay site, having 45 anuses instead of 45 years might be a thing...
