In a habitual manner; relating to or being a habitual action or characteristic.
From habitual (from Latin habitualis) plus the -ly adverbial suffix. Habitual itself comes from habitare ('to dwell' or 'to accustom'), reflecting how repeated dwelling creates familiarity and habit.
Linguists notice that 'habitally' is almost never used in favor of 'habitually'—it's a redundant form that lost the evolutionary battle in English, showing how language naturally prunes inefficient synonyms!
