I heard this during a radio broadcast this morning.

Problem:
This is a mispronunciation.

Explanation:
The radio broadcast was about The University of Texas Medical Branch at Galveston (UTMB).

The news reporter said that UTMB would not lose its “accredidation” in spite of yesterday’s announcement that 3,800 employees there would be laid off.

The noun is correctly spelled A-C-C-R-E-D-I-T-A-T-I-O-N because it comes from the verb “accredit”, which ends with a “t”.

Therefore, the final two syllables of the noun “accreditation” should be pronounced as “tation” (starting with a “t” as in “tango”) instead of as “dation” (starting with a “d” as in “delta”).

For fun, I searched Google for each of the following (without the quotation marks) and got about the indicated numbers of matches:

• “accreditation” — 38,100,000 matches
• “accredidation” — 85,500 matches

This tells me that Web authors have used the correct spelling versus the incorrect spelling by a ratio of 446-to-1, which is superb.

However, this ratio does not tell the complete story because it covers spellings, not pronunciations.

I believe that the mispronunciation of “accreditation” is consistent with my “Devolution toward Simpler” linguistic hypothesis. It is simpler to say “dation” than it is to say “tation”.

Solution:
“Accreditation”
