Correct spelling, explanation: the word controlled entered English in the early 15th century – at first it was spelled countrollen (meaning to check the accuracy of, verify; to regulate). It originates from Anglo-French contreroller and from Medieval Latin contrarotulus. It’s a derivative of the verb control. When we want to create a past participle or past simple of it, we must add the suffix -ed and double the consonant. Therefore, the only correct spelling is controlled, not controled.

Incorrect spelling, definition: the word controlled is a past participle and a past simple form of the infinitive to control. It is made of a basis and a suffix. There is a rule in the English language that when we have a single vowel before the last consonant in a word, we need to double that consonant. Although, many people forget that rule. That’s why the correct form is controlled and the incorrect one is controled.
