From Latin remediālis.
etymonline
remedial (adj.)
1650s, "curing, relieving, affording a remedy," from Late Latin remedialis "healing, curing," from Latin remedium "a cure, remedy, medicine, antidote, that which restores health," from re-, here perhaps an intensive prefix (or perhaps literally, "again;" see re-), + mederi "to heal" (from PIE root *med- "take appropriate measures").
Educational sense of "concerned with improving skills of students not as proficient as their peers or as required" is by 1879. In reference to physical exercise or training to overcome muscular or postural deficiencies, by 1925. Related: Remedially.
