Lyghiril

"The inhabitants of Pinnath Gelin, being for the most part uncouth shepberd-folk of Daen-stock, speak Sindarinwith such a strong accent that we often found it difficult to comprehend their utterances, which at any rate seemed largely concerned with sheep. Many among them find it difficult to pronounce vowel Y of Sindarin, and they regularly use U in its stead, so that we often heard forms such as urn "trees" and emun "hills" in place of proper yrn and emyn. The name of the river "Lûghiril" appearing on His Majesty's map thus reflects the local mispronunciation of Sindarin lyg "snake" as lug or lûg." -Findegil of Gondor

The Lyghiril (S."Snakeriver") was one of the streams that ran eastward out of the Pinnath Gelin of Anfalas into the lower Morthond Vale. Unlike its sister stream, the Calenhir, the Lyghirils headwaters actually exrended as far as the White Mountains themselves, a fact which accounted for the stream's twisting serpentine path through the hills of Anfalas. The Lyghiril was not navigable, and could be forded at most points along its course.
