Forward and Backward:

Forward and Backward are directional opposites used across grammar, idioms, and multiple technical fields. Depending on how you use them, they can describe physical movement, time, or a depth of knowledge. Grammar and Regional Differences

Adjectives vs. Adverbs: In strict grammar, forward and backward are adjectives (e.g., “a backward glance”). When adding an “-s” (forwards and backwards), they become adverbs describing an action (e.g., “he walked backwards”).

US vs. UK English: Authors writing in American English prefer dropping the “s” for both adjectives and adverbs (forward/backward). British English speakers regularly use the “s” variants (forwards/backwards) for actions. Common Idioms
