“ ‘The word “ca” [“and”] is used to connect a word or sentence with a previous word or sentence, to give the sense of aggregation, to assist the meaning, to give a collective understanding, to suggest another effort or exertion, or to fulfill the meter of a verse. It is also used in the sense of certainty.’
