altitudinal

adjective altɪˈtjuːdɪn(ə)lˈæltəˌt(j)ud(ə)n(ə)l

Origin

Late Middle English: from Latin altitudo, from altus 'high'.

Altitude is from Latin altitudo, from altus ‘high’. The latter is also the source of altar (Old English), a raised structure for worship, enhance (Middle English), originally ‘make higher’; exalt (Late Middle English), with ex- ‘out, upwards’; and haughty (mid 16th century), from altus via French haut.
