farlu -fal-fa'u- gismu

x1 falls/drops to x2 from x3 in gravity well/frame of reference x4.

Note: things can fall in spin, thrust, or tide as well as gravity; (agentive "drop" = one of two lujvo: falcru and falri'a). See also lafti, cpare, klama, sfubu.


In notes:

cpare
x1 climbs/clambers/creeps/crawls on surface x2 in direction x3 using x4 [limbs/tools].
klama
x1 comes/goes to destination x2 from origin x3 via route x4 using means/vehicle x5.
lafti
x1 (force) lifts/applies raising/supporting force to x2 at locus x3 in gravity well x4.
sfubu
x1 dives/swoops [manner of controlled falling] to x2 from x3.
falgau
g1 makes f1 fall.
rajroksfe
s1=rs1 is a vertical rock face / rock surface of rock / mountain rs2 on side rs3 with edges rs4, vertical in reference frame/gravity s2.
tolfa'u
f1 rises to f2 from f3 in gravity well/frame of reference f4.
