Question

which letter/letters is/are silent in word 'button' ?

Answer 1

‪Please note the ‘t’ is only pronounced as a glottal stop with certain dialects of English (famously, a London cockney accent, but also others).

In my (southern English) accent

I wouldn't glottal stop at all before a vowel / in the middle of a word. I would always pronounce the ‘tt’ in button. Unlike in Italian which would probounce both ‘t’s, British people would only pronounce one t - the double tt spelling is to indicate the short vowel for u (as in cup) rather than a long u (as in cute).

I only glottal stop before another consonant, for example ‘pit-stop’ (pi’stop) I would place my tongue to pronounce the t, but would not produce the plosion before the slide into the ‘st’. I would do the same for fat-dog (my dog is a fa’-dog). If I was speaking carefully in public, I may still pronounce the t in fat-boy (my dog is a fa’boy) but it's slipping here too

However I would caution non-native speakers against using the glottal stop, especially before vowels. Even though a Brit would recognise a glottal stop as an allophone for t from another Brit, in combination with a non-native accent it could make you difficult to understand.

Hope this may helpful
