ad-heer is how you pronounce the word.
Adhere is a verb because it describes a motion or movement.
Such as: "The glue adhered to her skin"
and "The mud adhered to his shoes"
Other ways to say this word can be past tense "Adhered" Or Present progressive "Adhering"
I believe the best time to use this word would be when you are playing sports such as Soccer or Football, maybe even track. Because it's those times when you are out on the field and mud really begins to stick to your shoes and cleates, which would cause damage and a sports player could tell his coach "But the mud is adhering on my cleates."

I find the word that is most in common with adhere would be glued. Because if you think about it, glue is very sticky and sometimes cannot be parted. Much like adhere, however, the only difference is the intensity of the two. Glued, in worst case scenarios, could very well be impossible to disjoin, however with adhere, it is possible to disjoin the two.
I would give the word a 2 out of 5, because in my opinion, I find more interest in words that could be used daily and without cause. However, with this word there has to some sort of cause to use this word, much like getting mud stuck to your shoe. Also, the use ratings are not very high. If someone were to get mud stuck on their shoe, it would be highly unlikely for someone to say "Mud is adhering to my shoe" rather than just saying "yo, I got mud on my shoes." This could very well be because of the popularity of the word which is not very popular and should only stick to being used in sports situations.
This is a good video because it shoes step by step how to adhere things on to a shoe. They also use the word multiple time in the video, giving you better understand of the word.
