verb (equals, equaling, equaled; also chiefly Britishequals, equalling, equalled)[with object]
late Middle English: from Latin aequalis, from aequus 'even, level, equal'
It is widely held that adjectives such as equal and unique have absolute meanings and therefore can have no degrees of comparison. Hence they should not be modified, and it is incorrect to say more equal or very unique on the grounds that these are adjectives that refer to a logical or mathematical absolute. For more discussion of this question, see unique (usage).
Do not double the final consonant when adding endings that begin with a vowel to a word that ends in a vowel plus a consonant, if the stress is not at the end of the word (as in target): (equals, equaling, equaled).
