Fathom, from father?
No, its roots are Germanic.
Googled, it hails from Faden, ‘six feet’
the span of two outstretched arms
‘something that embraces’.
How beautiful that was, to be fathomed by you.

Funny, the number of feet of an embrace
is the same as that of the earth
we are held by in our death.
Six solid feet of wet earth,
the last embrace—
but we don’t talk about that.
