This is from an e-mail message by somebody (I think an American, and a native speaker of English) in the financial industry:

We have inputted the necessary data and have begun ordering all the pertinent listings.

Apparently, the writer believes that there is a verb, to input, past tense, inputted.  And, for all I know, she or he is right!  I’ve always understood the noun input to be computer jargon for, that which is put in; but what do I know?

I have also always understood the word, putted, to be the past-tense form of the verb, to putt; but, again, what do I know?
