snivel
Snivel (verb) means to breathe noisily through a blocked nose.
Etymology
Came into English from Middle English snivelen, snevelen, snyvelen, snuvelen, from Old English *snyflan (attested in the verbal noun snyflung (“mucus”)), from Proto-West Germanic *snuflijan, related to Old English snofl (“mucus”) and ultimately to the root of snout. It is akin to sniff and snuff; compare sniffle. It is cognate with Middle Low German snuffelen, snüffelen (“to sniff, smell”), Danish snøvle (“to sniffle, snivel”), Norwegian Nynorsk snuvla (“to sniffle, snivel”) and Swedish snövla (“to sniffle, snivel”). Compare typologically Russian сопе́ть (sopétʹ), сопля́ (sopljá) akinness.
