I just looked it up online; it is My Fault, My fault, My most grievous fault; in latin. Just letting everyone know. God Bless and have a super day!
In this case, “mea culpa” does indeed mean “
through my fault.”
In Latin the endings of words change to signify their grammatical function in the sentence, so when the words are in the position of the grammatical subject of a sentence you might have, e.g., “Mea culpa est magna,” “My fault (=culpability) is great”; and when they are the object of a sentence, the endings would change and you might have “Odio meam culpam,” “I hate my fault.” To make the words possessive you change the endings again, for instance “Magnitudo meae culpae est magna,” “The magnitude of my fault is great.”
There is a grammatical function in Latin called the ablative case, which allows a word by itself to express things like causation in a way that in English requires additional words like “by” or “through.” So the English “through my fault” is rendered in Latin with just the words for “my fault,” but with the appropriate endings for the ablative case. In this situation, however, the ablative case of “mea culpa” is
also “mea culpa.” You just have to know enough Latin to recognize how the words are being used, but they are indeed being used in this sense, “through my fault, etc.”
Oh, and “maxima” really just means “largest” or “greatest,” and does not by itself carry any connotation of “grievousness.”
