Our Hunspell-derived misspelling index lists 6 documented wrong-spelling variants for slab, with forms such as "lsab", "salb", and "slabb".

Etymologically, the entry records: From Middle English sclabbe, slabbe, of uncertain origin; possibly from *slap, related to dialectal slappel (“portion, piece”), along with slape (“slippery”), sleip (“smooth piece of timber”), borrowed through Old Norse sleipr from Proto-Germanic *slaipaz, … Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is slab, spelled S-L-A-B, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
