There is no word for "a" or "the" in latin. If you want to use "a" or "the" in latin you would have to put it wherever it makes more sense in English (that is usually before a noun and sometimes after a verb).
The usual translation for "each" or "every" in Latin is omnis. "Everyone" and "everything" are rendered by plurals, omnes (masculine or feminine) and omnia (neuter) respectively.
Me poenitet - literally, 'It makes me sorry.'
Quod non necat fortior facit.
