Forms
lengþu f (strong ō-stem; genitive singular lengþe, nominative plural lengþa)[1] Also written lengþ, lengoþu and lengþo.[1] Bosworth and Toller head the word lengþ.[2]
Etymology
It is inherited from Proto-Germanic *langiþō (“length”), an abstract noun made to the adjective *langaz (“long”), the source of Old English lang.[1][3][4] The same noun appears as Old Norse lengd and Old Frisian lengithe, and Köbler sets up Old Saxon *lengithi beside them;[3][5][4] Orel adds Middle Low German lengde.[3][5][4]
Köbler traces the adjective to Proto-Indo-European *dlongʰos (“long”) (Pokorny's root *del-).[5] Kroonen takes *langaz as a nasalised variant of the root seen in Proto-Indo-European *dlh₁gʰ- (“long”).[6]
Earliest recorded meaning
The first dated record is in the Old English Orosius, in the Tollemache manuscript of the early tenth century: of Alexander's successors it says that Seleucus on lengðe mid him he begeat ealle þa eastlond “in the course of time gained with them all the eastern lands”.[7][8] Bosworth and Toller read the phrase on lengþe here as “at length”.[2]
Semantic evolution
The word is rare in the corpus, with two occurrences in prose.[8] Its main sense is length, the extent of a thing from end to end: the Peterborough Chronicle, in the annal for 1122, has a fire that weax on lengþe up “grew in length upward” to the clouds.[2][8] Toller's Supplement adds the sense height, from a prose text of the Solomon and Saturn group that measures a mountain in ðǽre lengoðe.[9] The phrase on lengþe of the Orosius is used of time.[2]
The word lived on as Middle English lengthe, now English length.[1][10]
