Pronunciation
Forms
tumeō (present infinitive tumēre); second conjugation, no passive, no perfect or supine stems[1]
Etymology
It is inherited from Proto-Italic *tum-ē-, inherited from Proto-Indo-European *tum-eh₁- (“to be swelling”), a stative verb from *tum- (“to swell”).[2][1] tumulus “mound” and tumor “swelling” come from it, and probably tumultus “uproar” too, though its formation is unclear.[2][3]
Cognate with Welsh tyfu (“to grow”), Sanskrit तुम्र (túmra, “strong, thick”), Lithuanian tumėti (“to become thick”) and Old Norse þumalfingr (“thumb”).[2][1]
Earliest recorded meaning
It is found from Plautus onwards,[2][4] who asks “what is this swelling on your neck?”.[3]
Semantic evolution
Its first sense was to swell or be swollen, of the body, as Ovid's body swollen with poison, and of the sea or a river running high, as in Virgil.[3][5] Figuratively it meant to be inflamed with anger or unrest, as in Cicero, and to be puffed up with pride, as Horace's “you swell with love of praise”.[3]
Of speakers and writers it meant to be bombastic.[3] English tumor (early 15th century) and tumult (late 14th century) come from its derivatives.[6]
Timeline
- c. 250–184 BC – Plautus uses it of a swelling on the neck.[3][4]
- 81–43 BC – Cicero uses it of a mind inflamed by anger.[3][5][4]
- 70–19 BC – Virgil uses it of swelling waves.[3][4]
- early 15th century – English tumor comes from its derivative tumor.[6]
