Q:

How to identify the sound of an "A" without altering the spelling of the word?

I have the word "Carr" (short for the name Carrie).
Is there a way to write the 'a' so that a person reading the word 'Carr' would pronounce it like care ('kær), opposed to pronouncing it like car (kɑr)?
Something like Càrr, Cárr, Cãrr, etc...?

A:

As John Lawler notes in the comments:

No. English spelling is not made to represent Modern English vowels, and deviating from standard spellings merely introduces more randomness.

The closest you can achieve is to completely alter the spelling to similar to CoolHandLouis' answer.
