The r is not silent in any of the words you mentioned, nor is it ever silent (that I know of).

Interested in Language
I found the following:-
carrot is r [not silent]
cry is r [not silent]
friend is r [not silent]
free is r [not silent]
garden is r [silent]
hear is r [silent]
German is r [silent]
here is r [silent]
four is r [silent]
learn is r [silent]
but I don't understand when R is silent or not? Is there a rule or can anyone explain it to me?
Thanks
The r is not silent in any of the words you mentioned, nor is it ever silent (that I know of).
Ron, you haven't lived in New England, where I'm called "Bahb."
R's that follow a vowel sound will sometimes fade away. I believe officially it's called the "non-pre-vocalic r."
The R in carrot is clearly pronounced because of the second syllable.
R's that are end the end of the word can fade away as well, or take an "uh" sound.
Dear sounds like dee-uh and beer sounds like bee-uh. But this is distinctive to certain areas.
However, I would pronounce the R in all of those, as Ron would. (Even though when someone calls out "Bob!" I still turn around.)
The R is much less pronounced in England and Wales.![]()
In RP most of the R's are silent. They disaapear before consonants and at the ends of words. R's are audible when occur between vowels or when folled by a vowel. Hence:
carrot is r [not silent]
cry is r [not silent]
friend is r [not silent]
free is r [not silent]
(all of R's are folled by vowels in examples above)
In the following examples R's are muted beacuse they're preceeded by vowels which turned to be longer thanks to disapearing R's.
garden is r [silent] --> /ɑ:/
German is r [silent] --> /ɜ:/
four is r [silent] --> /ɔ:/
learn is r [silent] --> /ɜ:/
Finally, R's in the following exaples turn into vowel schwa /ə/
hear is r [silent] --> /hɪə/
here is r [silent] --> /hɪə/
I hope it helps at least a little![]()
We have a restaurant ad running in some of our TV channels in which the announcer is I believe British. It’s very distinct to hear how the end ‘r’ were dropped in words like “texture” & “adventure” in RP English as Tdol & Seba indicated.
It's not universal in Britain- England and Wales tend to be non-rhotic (don't pronounce the R) and Scotland is generally rhotic.
