'management' originates from Italian (via Old French), specifically from the Italian verb 'maneggiare' (to handle, esp. of horses) and Latin 'manus' meaning 'hand'; 'forest' originates from Old French 'forest', from Medieval Latin 'foresta' meaning 'outside, woodland'.

'maneggiare' passed into Old French as forms of 'manage' (via medieval Italian/French usage) and later became English 'manage', with the noun 'management' formed in Modern English; 'foresta' became Old French 'forest' and entered Middle English as 'forest' (often denoting land reserved for hunting) before broadening to mean woodland.

Initially, 'management' (rooted in 'manus') had a sense of 'handling by hand' and evolved to mean 'organizing or directing'; 'forest' originally often meant an area 'set aside (for hunting)' and over time shifted to the general meaning 'woodland' or 'woods'.
