Please help me to sought out this difficulty:
" they have had to postpone the meeting".
“I have had my post graduate degree from Cambridge University”. :?
“Rachael has had a bad cold for last two days”. :?
In which sort of circumstances do we use this pattern " have/has+had+noun :?:
Which tense does these sentences indicate? please clearify this topic full well and please correct me also if I use incorrect tense or any other grammatical rule in the written post.
I shall be highly thankful to your attention.
