Did You Know?

Above I use the phrase "through and through". Ano nga ba ang tama ... through and through ... or thru and thru?

The correct phrase is "through and through" as "thru" is considered an informal abbreviation of "through" and should generally be avoided in formal writing; "through and through" means completely or thoroughly. 

THROUGH is the only formally accepted spelling of the word. THRU is an alternate spelling that should be used only in informal writing or when referring to drive-throughs/drive-thrus.

Both "WALK THRU" and "WALK THROUGH" are acceptable depending on the context. “Walk thru” and “walk through” mean the same thing: To move through a place. To go over something carefully.
