I personally would not choose it.
I don't have a solution ready... Perhaps:
Early Noldorin neb "near" is quite close to Sindarin nef "on this side of"; perhaps an expression like *nef pain (*phain?) 'near all' or *nef p(h)ant 'near full'?

+Hjalmar Holm +Tamas Ferencz or/athar pherth 'above/more than half'? That's working, and that describes a 'majority' for me!

+Александр Запрягаев Where do you find perth? I find perin as Noldorin for "half".

+Hjalmar Holm perta as an ancient word for 'half', in VT48.

lae(wed) (with or without some augmentative prefix/suffix)?

ammeleg (vs. Nold. goriad) 'greater' +abstract noun suffix?

* orchal-lim (L < R) ?

* eir–, rod–ovras, –choth, –wanod (*eir– < *arjâ) ?

* g(w)ebin rórim (~ 'most persons', umlaut plural noun + adj) ?

*orchallim, the lofty host!
ammeleg, mightiest, a good word, but can mean a very powerful minority
* eir–, rod–ovras, –choth, –wanod seem all to mean "beyond numbers" and similar.
What I thought of was to say something like "Most of the Hobbits of the Bree-land lived in Staddle", but the hobbits in Staddle are not "beyond numbers" or even "very many", just more than the other hobbits in Breeland. Here or pherth (above half) or rórim (most populous?) might work! I did'nt understand *gwebin though. 

+Hjalmar Holm,
Presumably *g(w)ebin is the plural form of  pen (Q quén) preceded by go-, gwa-.

I'm familiar with  the go-, but the form gwa- confuses me. Thanks +Matt Dinse . gwebin sounds to me like "common, communal", adjective, like in  something belonging to the peoples (a language, a field, a tradition, a town or what not).
