Please, please don’t say “GhhthfFghTtTghfnfG!”. Final “GHT” is simply pronounced /t/
Yes, I know this combination of letters, “GHT” is strange looking – I agree. Many people are intimidated by words with this group of consonants (called a consonant cluster).
When they try to say these words, the confusion intensifies. They think: Is it “G”? if it “F”? is it “T” is it “GaHa”? “HaTa” “FuFa” ? Usually they panic and in the end make very strange noises like “GhhhFghTtTghfff!”. Please, don’t do this to my language. The answer is, as usual, very easy: you only have to say /t/. There are almost *no exceptions to this.
“GHT” = “T”
Are you thinking, “If it’s this simple, why is everyone so confused?” The problem is that people confuse “GH” and “GHT”. But don’t worry, the answer is still quite simple.
When there is “GH” at the end of the word, there are only two possibilities /f/ or /no sound/.
“GH” = “F”
“GH” = silent:
Knowing if “GH” is “F” or silent is a matter of memorization. The good news is that there are not many of these words.
The “Right” /t/ way to speak is easy “enough” /f/, no?
* “Draught” is one of the extremely rare exceptions. Here “GHT” is pronounced /ft/. In many cases the more modern spelling has been changed to reflect the pronunciation. In many cases “Draft” is used in place of “Draught”. Another more common exception is “laughter”. Here the “ght” is also pronounced /ft/.
