oþh

oþh is a textual sequence formed by the Latin letter o, the thorn letter þ, and the Latin letter h. The character þ (thorn) was used in Old English, Old Norse, and related medieval scripts to represent the sounds typically written as "th" in modern transcriptions, often denoting /θ/ or /ð/ depending on language and position. The combination oþh is not known as a standalone lexical item in standard Old English or Old Norse dictionaries.

Because oþh does not appear as a defined word, it is most likely to be found only as a fragment within a longer word, a scribal abbreviation, a misreading in manuscript transmission, or an interlinear gloss in a marginal note. Its lack of a fixed meaning means it is primarily of interest for studies of orthography, palaeography, and manuscript transmission rather than lexicography.

In textual analysis, such sequences illustrate orthographic practices and the transition from thorn-based writing to the digraph "th" in later Latin-script alphabets. The arrangement of thorn with adjacent letters can affect parsing in palaeographic editions and transcriptions, making careful reading important for accurate textual reconstruction.

Encoding and typography: the sequence is written with o (U+006F), thorn (U+00FE), h (U+0068). In modern contexts, thorn is often transliterated as "th."
