A forward tilt (横強攻撃, Side strong attack), also known as an "f-tilt" or "side tilt" (the lattermost the official name as of Ultimate, otherwise called strong side prior to its release) is a tilt attack performed by holding the control stick forward and pressing the attack button while on the ground. This is distinct from a forward smash in that the control stick is only tilted, not tapped. Forward tilts are generally simple, quick, weak outwards strikes for close-quarters combat.
Some forward tilts can be angled up or down to some extent, pointing the hitbox in a diagonal direction instead of totally forward. Most attacks that are angled up are slightly more powerful than if they weren't angled, while some are weaker if angled downwards.
