For example, look at the word 'patient' in these sentences:
The hospital has beds for 800 patients
You need to wait a little longer, please be patient
And what about the words 'meat' and 'meet'? They sound exactly the same too:
Meet me at 8 o'clock at the market
I bought 8kg of meat at the market
We call words which sound the same 'homophones'. If they sound the same and have the same spelling too we call them 'homonyms'.
