How can I express "bottom" superlative?

single-word-requests superlative-degree

Solution 1:

You should use bottommost and topmost. The postfix "most" shows physical position. Use the postfix "most" with adjectives that compare three or more things.

If you have two coins, do not use bottommost and topmost. You'd use bottom coin or top coin. If you have three coins, two are potential bottom coins, since only one is on the top. Because there are more than two possibilities to be the bottom coin, it is appropriate to use bottommost to refer to the coin on the opposite end of the top.

Bottommost: Situated at the very bottom.

Topmost: Situated at the very top.

Solution 2:

The one at the bottom is the "bottommost" coin.
