Not exactly a fit subject for a referendum.
Seems like the subject IRA is an acronym--Individual Retirement Account.
Sometimes acronyms are pronounced as if a synthetic word- if judged euphonious- S.W.A.T. for example.
Other times spoken out as a string of letters-- U.S.A., G.D.R., etc. (etc. is an abbreviation, not an acronym-- spoken as if not abbreviated at all, except occasionally spelled out- no euphony to be found there)
Usage is inconsistent, so it's your choice. No penalty points awarded, either way.
