I quite enjoyed browsing through some of the entries. Here’s a couple of selections:
Definition: A compound expression that creates a metaphorical synonym for another, more mundane noun.
(1) oar-steed (a ship)
(2) storm of swords (battle)
(3) whale road (the sea)
Note: Kennings were common in Norse oral literature. For example, the name Beowulf was coined from the kenning beo wulf, bee wolf (i.e., a bear, because bears like honey).
Etymology: The word derives from the Old Norse kenna eitt við, express one thing in terms of another.
Note: the word derives from a mediæval Icelandic work on poetics.
OED: The term’s first OED citation is from 1883: “The extreme development of the ‘kenning’ in Northern Poetry.”
(Vigfusson & Powell Corpus Poet. Bor. II. 448)

(170 BCE — 90 BCE) A Greek grammarian who lived and worked in Alexandria and, purportedly, wrote the first proper Greek grammar — the Art of Grammar (Tékhnē grammatiké).
In his book, which only dealt with word morphology (the study of sentence syntax had to wait 300 years for Apollonius Dyscolus’ work), he introduced the idea that there are eight parts of speech.
Though Thrax’s concept only pertained to Greek, the idea that there are just eight parts of speech greatly influenced subsequent Latin and English grammarians.
Note: He was called Thrax because his father was a Thracian.
