When you read sentence, for example, "I lost my pencil." People usually silence 't' at 'lost'.
But do I silence 'ge' in this sentence?
"I want to eat large cheese pizza."
Why or why not? and how do I know when to silence last word?
I'm not a teacher. I speak American English. I've tutored writing at the University of Southern Maine and have done a good deal of copy editing and writing, occasionally for publication.
You have worded your question badly. I think you meant "Why do people sometimes silence the last letter of some words in a sentence?"
You are right about "I lost my pencil". Unless someone is speaking very carefully, it's easy for them to fail to completely enunciate the "t" at the end. If they're speaking fast, they might say it but you might not hear it.
I can't think of any circumstance in which the "ge" (J sound) would be omitted from the end of the word "large". That would leave the word "lar" which makes no sense. However, the combination of "large" and "cheese" does mean that the end of the first word runs into the beginning of the second word. Because the sounds are very similar, and because we don't leave a pause between them, it might sound like we're just making one sound. We're not, we're still saying "large cheese".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
