More about encumber
Encumber 鈥渢o impede or hinder鈥� derives via Middle English from the Anglo-French noun combre 鈥渄am, weir鈥�; just as encumber involves restricting action, the purpose of a dam is to restrict the movement of water. Combre ultimately comes from unattested Gaulish comberos 鈥渃onfluence, bringing together,鈥� which may derive from two Proto-Indo-European roots: kom 鈥渨ith鈥� (compare the Latin-derived prefix co- 鈥渢ogether鈥�) and bher- 鈥渢o carry, bring鈥� (compare English bear and the -fer element in the Latin-origin verbs prefer, refer, and transfer). Encumber was first recorded in English in the early 1300s.

Around half of all people with these mutations depend on blood transfusions throughout their entire lives. The quality of that life is encumbered, and its length might be curtailed. The only cure is a transplant of blood stem cells from a close relative or preferably an identical twin. As you might imagine, that鈥檚 not always possible and even when it is, it鈥檚 a risky procedure with no guarantee of success.
More about hiemal
Hiemal 鈥渙f or relating to winter鈥� comes from Latin adjective 丑颈别尘腻濒颈蝉, of the same meaning, from hiems 鈥渨inter.鈥� Another adjective related to hiems is 丑墨产别谤苍耻蝉 鈥渨intry,鈥� which is the source of hibernal and hibernate. Hiems comes from the Proto-Indo-European root ghei- 鈥渨inter,鈥� which is also the source of Ancient Greek 肠丑颈峁搉 鈥渟now鈥� and 肠丑别颈尘峁搉 鈥渨inter鈥� as well as Sanskrit hima 鈥渟now,鈥� as in Himalayas, the mountain range in southern Asia. The English word winter, in contrast, derives instead from the same root as water and wet. Hiemal was first recorded in English in the 1550s.

The air through which it raced was thin, with less than one per cent of sea-level pressure, and at sixty below as deadly cold as the most hiemal places on earth, but despite that the matt-black [sic] titanium alloy skin of the aircraft seared with enough heat to vaporise a hand.
ecliptic
noun

More about ecliptic
Ecliptic 鈥渢he circle formed by the intersection of the plane of the earth鈥檚 orbit with the celestial sphere鈥� comes by way of Middle English and Medieval Latin from Ancient Greek 别办濒别颈辫迟颈办贸蝉 鈥渙f an eclipse,鈥� from the verb 别办濒别铆辫别颈苍 鈥渢o leave out, 鈥渢o fail to appear, to forsake one鈥檚 place.鈥� These latter senses of 别办濒别铆辫别颈苍 inform the definition of eclipse, an event in which the sun or moon refuses to appear. 贰办濒别铆辫别颈苍 comes from the Proto-Indo-European root leikw- 鈥渢o leave鈥� and is related to the English numbers eleven and twelve, from Old English endleofan and twelfe, literally 鈥渙ne left over鈥� and 鈥渢wo left over鈥� (after counting to ten). An additional relative is the Latin verb linquere 鈥渢o forsake, leave, quit鈥� (as in delinquent, derelict, and relinquish). Ecliptic was first recorded in English in the late 1300s.
how is ecliptic used?
The reason all of the planets and our moon pretty much take the same ecliptic path among the stars is that they, along with our Earth, all orbit the sun in the nearly [sic] the same geometric plane. They also move along the ecliptic at different speeds. The planets close to the sun, like Venus and Mercury are on a celestial caffeine high, and they zip along the ecliptic because they whip around the sun much faster than outer planets like Uranus and Neptune, that really take their sweet time completing the ecliptic circuit. Consider the ecliptic the long and winding road in the stars.
The planets in our solar system mostly orbit around the Sun in a disk known as the ecliptic. Mercury and Pluto are the outliers, but the others only vary by a few degrees from this plane. This happens around other stars as well. However, the ecliptics of other stars are not necessarily lined up with our point of view. The farther off the ecliptic we are, the less likely we are to see a transit …. Distance factors in here, as well. The closer a planet is to its star, the farther off the ecliptic we can be and still see a transit. For planets farther away from their star, we need to be viewing the system from close to edge-on.
