A word in the Declension of Nouns (DN) of the early 1930s glossed “a press”, a combination of the verbal element ᴹQ. sanga- with the instrumental suffix ᴹQ. -ma (PE21/8), hence more literally a “✱thing that presses”.
Quenya
nir-
press, thrust, force (in a given direction)
nir-
verb. press, thrust, force
nir- vb. "press, thrust, force (in a given direction)" ("Though applicable to the pressure of a person on others, by mind and 'will' as well as by physical strength, [this verb] could also be used of physical pressures exerted by inanimates.") Given as a 1st person aorist nirin (VT41:17). Pa.t. probably *nindë since the R of nir- was originally D (the base is given as NID; compare rer- pa.t. rendë from RED concerning the past tense)
