tho.

1. Grant; admit; allow. "If thy brother be waxen poor--thou shalt relieve him; yea, though he be a stranger." Grant or admit the fact that he is stranger, yet thou shalt relieve him. Leviticus 25:35.

Though he slay me, yet will I trust in him. Job 13:15.

That is, grant or admit that he shall slay me, yet will I trust in him.

Though hand join in hand, the wicked shall not be unpunished. Proverbs 11:21.

That is, admit the fact that the wicked unite their strength, yet this will not save them from punishment.

Not that I so affirm, though so it seem.

That is, grant that it seems so, yet I do not so affirm.

2. Used with as.

In the vine were three branches, and it was as though it budded. Genesis 40:10.

So we use as if; it was as if it budded; and if is gif, give. The appearance was like the real fact, if admitted or true.

3. It is used in familiar language, at the end of a sentence.

A good cause would do well though.

This is generally or always elliptical, referring to some expression preceding or understood.

4. It is compounded with all, in although, which see.
