تعسّر

It (spun thread, غَزْلٌ, in the K قَوْلٌ [speech], but this is a mistake, TA) became entangled, so that it could not be unravelled; as also تغسّر, with the pointed غ: so according to Lth, as related by Az, who confirms it as of the language of the Arabs: but Sgh, in the TS [and O], says, You say of a thing, when it has become difficult, استعسر and تعسّر; but of spun thread, when it has become entangled, so that it cannot be unravelled, تغسّر, with the pointed غ; not with the unpointed ع, unless using a forced, or constrained, mode of speech.
