ADD, verb transitive [Latin addo, from ad and do, to give.]

1. To set or put together, join or unite, as one thing or sum to another, in an agreegate; as, add three to four, the sum is seven.

2. To unite in idea or consideration; to subjoin.

To what has been alledged, let this argument be added.

3. To increase number.

Thou shalt add three cities more of refuge. Deuteronomy 19:9.

4. To augment.

Rehoboam said, I will add to your yoke. 1 Kings 12:11.

Ye shall not add to the word which I command you. Deuteronomy 4:2.

As here used, the verb is intransitive, but there may be an ellipsis.

To add to, is used in scripture, as equivalent to give, or bestow upon. Genesis 30:24, Matthew 6:27. In Galatians 2:6, the word is understood to signify instruction. 'In conference they added nothing to me.' In narration, he or they added, is elliptical; he added words, or what follows, or he continued his discourse.

In general, when used of things, add implies a principal thing, to which a smaller is to be annexed, as a part of the whole sum, mass, or number.
