A man or youth
The man (speaking of a singular person, not "the man" as in police or government)
Dabar tu - mano pasaulis; Dabar tu esi mano pasaulis. [da'bar 'tu e'si 'mano pa'saulis]
Sostén tu mano
Una mano is Spanish for 'a hand'
"mano" in Italian means "hand."
"Su mano derecho" means "his/her/your right hand."
Contrary to popular misconception, "mano a mano" does not mean 'man to man.' It is a Spanish phrase literally translated as 'hand-to-hand,' usually used in the context of combat or competition. In English, many people incorrectly use the expression "[to] talk mano a mano" to mean "[to] talk one-on-one." But it really means something more like "[to] go head-to-head."
Antanas Jonynas has written: 'Puodai savo vietose' 'Tu--mano kraujas gyvas'

bajo mano = underhand bajo la mano = under (the) hand *Please, read carefully because it is "BAJA" (a verb), not "bajo" (a preposition).
"Hecho por mano"
If you mean 'mano' that's 'hand'.
