You appear to be reading the GNU troff manual corresponding to the _groff_
1.23.0 release.
Subscripting strings are a new feature of _groff ms_ in 1.23.
Also see:
https://git.savannah.gnu.org/cgit/groff.git/tree/NEWS?h=1.23.0#n457
o The s (ms) macro package has added strings, `<` and `>`, to perform
subscripting. They work analogously to the `{` and `}` superscripting
strings that have been present in groff ms since 1991 or earlier.
Please upgrade to _groff_ 1.23.0 to get the benefit of this feature.
If that is infeasible, you can copy the definitions of these strings into your
document until 1.23.0 is available to you.

.\" subscript
.ds par@sub-start \v'+.3m\s'\En[.s]*7u/10u'-.1m'
.als < par@sub-start
.ds par@sub-end \v'+.1m\s0-.3m'
.als > par@sub-end
Does this help?
