mood1 feeling

Confidence
Established
Formation
Inherited
First attested
a. 900
Inherited from
Old English mōd via Middle English
Ultimate origin
Proto-Germanic (*mōdą)

Etymology

It is inherited from Middle English mod, mood, inherited from Old English mōd (“mind, heart, spirit; courage, pride”),[2][1][5] from Proto-Germanic *mōda-,[2] the source also of Dutch moed and German Mut “courage”, Old Norse móðr “anger” and Gothic mōþs “courage, anger”.[2][1][6] Its further origin is unknown, and Boutkan finds no acceptable Indo-European etymology,[2][6] though Barnhart and MWU relate it to Latin mōs “custom”.[1][5]

Earliest recorded meaning

Mind, heart, thought, feeling: before 900 in the OED, a sense now obsolete.[7] Barnhart has Old English mōd in Beowulf about 725.[1]

Semantic evolution

It was a much stronger word in Old English than now, used in compounds such as modcræftig “intelligent” and modful “proud”.[2] Anger is from about 1175, and fierce courage or pride from about 1205; both are obsolete.[7] A frame of mind or state of feeling is from 971 in the OED, about 1300 in Etymonline.[7][2] In the mood is from the 1580s,[2][7] a fit of bad temper by 1859,[2][7] and mood music and similar uses from 1898.[7] Mood swings is by 1939.[2] Trench noted that the grammatical mood seems to have influenced this word.[3][2] Moody first meant brave or proud.[1][6]

Etymology

It is an alteration of mode under the influence of mood “feeling”,[1][2][5] from Middle English mode, borrowed from Old French mode and directly from Latin modus (“manner”).[1][2]

Earliest recorded meaning

In grammar, a form of a verb showing whether the action is a fact, a command and so on: 1569 in MWU, 1573 in Barnhart, the 1570s in Etymonline.[5][1][2] Middle English mode had this sense from about 1450.[1]

Semantic evolution

In traditional logic it is from the 1560s, and in music from the 1590s.[2] Etymonline notes that the two moods have no etymological relationship, although the grammatical and musical uses influenced phrases such as light-hearted mood.[2]
