What does directional mean?
Directional is an adjective describing anything that relates to, indicates, or operates with respect to a particular direction. Its most familiar uses are physical and technical: a directional sign points travellers along a route, a directional microphone captures sound mainly from one side, and a directional antenna focuses its signal toward a specific target rather than broadcasting in every direction. The word also extends to figurative contexts, where a directional decision or piece of advice sets a course for future action without dictating details — as when a leader offers directional guidance on strategy. Derived ultimately from Latin dīrigere, meaning to straighten, guide, or align, it entered English through the noun direction plus the adjectival suffix -al. Directional carries a neutral, often practical connotation and is especially at home in engineering, navigation, audio production, oil drilling, and business planning. A useful companion term, omnidirectional, names its opposite: operating equally in all directions.
Relating to or showing direction; designed to send, receive, or point along a particular line or bearing.
"The engineers used directional drilling to reach the oil pocket from a site two miles away."
Often found before nouns in fixed technical pairings such as directional antenna, directional microphone, and directional sign.
Providing general guidance about the course or development of something rather than detailed instructions.
"The board gave only directional feedback, leaving the specifics to the project team."
Frequent in business and policy writing; the phrase 'directionally correct' means broadly right even if imprecise.
Without directional microphones, your phone couldn't pick out your voice from the noise of a crowded street — the same physics that lets an antenna aim at a satellite.

Etymology of directional
Directional derives from the noun direction, combined with the adjectival suffix -al. Direction itself comes from Latin dīrectio, formed from the verb dīrigere, meaning to straighten, set upright, guide, or align, built from dis- ('apart') and regere ('to rule or direct straight'). The word entered English via Old French and Latin during the Middle English period, while directional as an adjective developed later, becoming established by the nineteenth century alongside growing scientific and navigational vocabulary. It shares this Latin root with words such as direct, erect, and correct.
How directional is actually used
Neutral to technical register; common in engineering, navigation, and audio contexts. The figurative use for strategic or policy guidance is frequent in business and political writing. The related adverb 'directionally' appears mostly in analytical and business prose ('directionally correct').
