I need help using grep

What is the syntax for using the grep utility to find all 8 character words in a long list of words that contain the letter 't'?
# 2  
What is your list look like?
# 3  
I think the list of words is the built in dictionary in Unix. It is located in /usr/dict

the list goes like this:

Animal
Beer
category

etc....

I tried doing:

grep '[t.......t*' /usr/dict

but i get all the words that contain 't' and not the ones with 8 characters.
# 4  
egrep ^.....$ a1 | grep t

where ..... : represents number of characters u want in the word.
Here for eg: it represents a word with 5 characters

Regards,
Jigar

Alternative, in awk: Smilie

awk '{if (length() == 8 && /t/) print}' /usr/dict
# 6  
thanks guys!
