What does altho mean?
'Altho' is a shortened spelling of the familiar conjunction 'although', pronounced identically (/ɔːlˈðoʊ/) and serving exactly the same function: it introduces a concessive clause that states a contrasting or qualifying fact alongside the main statement of a sentence. For example, one might write 'altho the forecast promised rain, we hiked the whole ridge in sunshine.' The form arose as an economy spelling, trimming a single letter from 'although', and it was promoted by early twentieth-century advocates of simplified spelling in the United States. Despite that endorsement, it never displaced the full form in mainstream writing, so today it appears mainly in informal contexts, older texts, and dictionaries that list variant spellings. Writers who encounter it should treat it as equivalent to 'although' in meaning, but those composing formal prose, journalism, or academic work will almost always choose the standard spelling instead. Its interest lies chiefly in this glimpse of how even small typographic economies can linger on the margins of English usage.

'Altho' drops just one letter from 'although', yet it has been championed by style reformers for over a century as a leaner way to write the same word.

Etymology of altho
'Altho' descends from the Middle English phrase 'all though', itself built from 'all' plus 'though', which traces back to the Old English concessive word 'þēah'. The compound 'although' became the standard spelling, while 'altho' emerged later as a deliberate economy spelling, notably promoted by American simplified-spelling advocates in the late nineteenth and early twentieth centuries. It shares its ultimate root with the related concessive forms 'though' and constructions like 'albeit' and 'howbeit'.
How altho is actually used
