Find and replace using regular expressions - remove double spaces between letters only

Trying to do this in the Atom editor (1.39.1 x64, uBuntu 18.04), though assume this applies to other text editors using regular expressions.

Say we have this text:

This text has some double-spaces. Lets try to remove them. But not after a full-stop or if three or more spaces.

Which we would like to change to:

This text has some double-spaces. Lets try to remove them. But not after a full-stop or if three or more spaces.

Using Find with Regex enabled (.*), all occurrences are correctly found using: [a-zA-Z] [a-zA-Z]. But what goes in the Replace row to enforce the logic:

1st letter, single space, 2nd letter?

You can use this

([a-z])\s{2}([a-z])

and replace by $1 $2

enter image description here

Regex Demo

If your editor supports lookarounds you can use

(?<=[a-z])\s{2}(?=[a-z])

Replace by single space character

Note:- don't forget to use i flag for case insensitivity or just change the character class to [a-zA-Z]
