Ten-Letter Mystery (1/31)

I'm thinking of a common ten-letter word. I found a set of three different letters within this word which repeat themselves back to back and in the same order. The leftover letters are as follows:

STOME.

If you imagine the deleted letters to be represented by 123, then you might insert them twice within the word like this:

S123123TOME.

This is not necessarily where the inserted letters belong, but they will appear as the pattern 123123.

What is the word?
