If BAR depends on FOO – in the sense of “BAR has FOO as a prerequisite” – I can use the term “dependency” for one end of that relationship:
BAR has a dependency on FOO.
What is an equivalent, simple term for the opposite relationship:
FOO is a is-depended-on-by for BAR
I'm seeking a generally-applicable answer, so FOO and BAR are just placeholders for entities.
The noun should work as one of a collection of terms, “FOO is a recommendation for BAR”, “FOO is a suggestion for BAR”.
- BAR suggests FOO ⇒ FOO is a suggestion from BAR
- BAR recommends FOO ⇒ FOO is a recommendation from BAR
- BAR depends on FOO ⇒ FOO is a noun-for-other-end-of-the-dependency-relation from BAR
Note that these terms – “suggests”, “recommends”, “depends” – are not open for me to change. I am looking for the term at the other and of each of those named relations.
- The hockey rulebook suggests the Pickworth tie breaker ⇒ The Pickworth tie breaker is a suggestion from the hockey rulebook
- The city guidebook recommends the seven-day rail pass ⇒ The seven-day rail pass is a recommendation from the city guidebook
- The state budget depends on the federal tax concession ⇒ The federal tax concession is a noun-for-other-end-of-the-dependency-relation from the state budget
What term goes in that place in the depends–is-depended-on relationship?
The answers to ““Employee” is to “employer” as “dependent” is to what?” don't apply, because those are specifically about people (and carry all the baggage of that, e.g. parent–child, sponsorship, etc.) that are not generally applicable.
The answers to “A depends on B, is A dependant, or is B dependant?” address the issue of parts of speech, which is not the subject of this question.
What is a noun which describes the relationship from the depended-on side?
