That is interesting. I would pronounce all of those names with the AHR sound instinctively, although I do recognize that other people might pronounce
Clara,
Sara, and
Tara with the AYR sound. CLAYR-uh seems like an alternative pronunciation of CLAHR-uh to me, whereas to get SAYR-uh I feel as though it should be spelled
Sarah and
Sara is SAHR-uh. I hate the pronunciation TAYR-uh for
Tara; it drives me crazy.
Terra I would pronounce TAYR-uh, but I'm not a big fan of that name.
(For reference: I live in Texas but I grew up in the UK and have a British accent. My parents are from different parts of the US. So my vocabulary and pronunciation influence is a bit jumbled.)
LISTEN TO THE MUSTN'TS
-
Shel Silverstein
Listen to the MUSTN'TS, child,
Listen to the DON'TS
Listen to the SHOULDN'TS
The IMPOSSIBLES, the WON'TS
Listen to the NEVER HAVES
Then listen close to me—
Anything can happen, child,
ANYTHING can be.
