Quick Definition
στρωννύω v. I spread, make a bed
Strong's Definition
stronnuo strone-noo'-o, prolongation from a still simpler stroo stro'-o, (used only as an alternate in certain tenses) (probably akin to 4731 through the idea of positing); to "strew," i.e. spread (as a carpet or couch)
KJV Usage: make bed, furnish, spread, strew
UBS Dictionary of the Greek New Testament
verb | καταστρώννυμι · λιθόστρωτον · ὑποστρωννύω
16.22 · (στρώννυμι[a]) · Non-Linear Movement
to spread, to spread out to spread something out
46.9 · (στρώννυμι[b]) · Household Activities
to furnish, to arrange to fit out or arrange a room in a suitable manner (that is, to provide it with necessary furniture)
46.10 · (στρώννυμι[c]) · Household Activities
to make one’s bed to prepare a bed, either for sleeping or making it up after it has been used
1 It is possible to argue that στρώννυμι (and the corresponding form στρωννύω) has only the base meaning to spread something out (as in MAT 21:8; see 16.22), but this term seems to be used in an absolute sense in rather highly diverse contexts, and therefore one is justified in setting up more than one distinct meaning.
