Careful: 'offensiv' does not always mean the same as the English word 'offensive'. While 'offensive' usually means 'beleidigend' (insulting/offensive), 'offensiv' in German often simply means 'attack-oriented' or 'proactive', especially in sports or discussions.
Die Mannschaft spielte sehr offensiv, um ein Tor zu schießen.
The team played very offensively in order to score a goal.
The meaning of 'offensiv' depends strongly on the context. In sports, it is about attack; in a discussion, it is about a proactive stance; and only in the case of hurtful behavior does it mean 'offensive' or 'insulting'.
Seine offensive Spielweise ist riskant, aber oft erfolgreich.
His attacking style of play is risky, but often successful.
In a sports context, 'offensiv' describes a tactic or style of play that is focused on attacking. Typical combinations are 'offensiv spielen' (to play offensively), an 'offensive Aufstellung' (attacking lineup), or an 'offensiver Spieler' (attacking player).
Der Trainer entschied sich für eine offensive Taktik.
The coach decided on an attacking tactic.
In the meaning 'challenging' or 'proactive', 'offensiv' is often used as an adverb. It then describes the way someone acts or communicates, e.g. 'ein Thema offensiv ansprechen' (to address a topic proactively) or 'eine Meinung offensiv vertreten' (to express/defend an opinion assertively).
Sie hat das Problem im Teammeeting offensiv angesprochen.
She addressed the problem proactively in the team meeting.
aggressive
When describing business strategies, aggressiv and offensiv can both describe an energetic approach. Aggressiv additionally emphasizes strong pressure or a lack of consideration, while offensiv highlights initiative and active action in a more matter-of-fact way. Choose offensiv for a focused strategy and aggressiv when the pressure is particularly clear.
