What does antitakeover mean?
Antitakeover describes anything designed to prevent or frustrate the hostile acquisition of a company — typically provisions, defensive structures, or statutes that make an unwanted takeover more difficult or expensive for a bidder. The word operates almost entirely within corporate finance, securities regulation, and business journalism, where it commonly modifies terms such as 'measures', 'provisions', 'devices', 'defenses', and 'statutes'. Familiar examples of antitakeover tactics include staggered boards, supermajority voting requirements, golden parachutes, and the notorious 'poison pill', which dilutes a raider's stake. The term carries a neutral-to-defensive connotation: it frames management and boards as protecting corporate independence, though critics sometimes view heavy antitakeover machinery as entrenching incumbents at shareholders' expense. Because mergers-and-acquisitions activity is a permanent feature of modern capitalism, antitakeover remains a durable and precise piece of business vocabulary worth recognizing in financial news and legal writing alike.
Serving to prevent, resist, or deter a hostile takeover of a company.
"The shareholders approved new antitakeover provisions at the annual meeting."
Almost always used attributively before a noun such as 'measures', 'provisions', 'defense', or 'statute'.
A measure, provision, or device designed to prevent or resist a hostile takeover.
"The staggered board was widely regarded as an effective antitakeover."
Less common than adjectival use; usually refers to a specific defensive mechanism.
Rare; the plural appears only when referring collectively to multiple defensive mechanisms, as in legal or financial commentary.
"The company deployed several antitakeovers, including a poison pill and a staggered board."
Some antitakeover devices are so aggressive they're nicknamed 'poison pills' — deliberately making a company less appetizing to swallow.

Etymology of antitakeover
The word combines the Greek-derived prefix 'anti-' (meaning 'against') with 'takeover', a twentieth-century English compound from the verb 'take'. 'Take' itself descends from Old Norse 'taka', absorbed into English during the Viking-age settlements, which makes related forms such as 'intake', 'mistake', 'partake', and 'undertake' distant cousins sharing that Scandinavian root. 'Takeover' emerged in early twentieth-century commercial usage as corporate acquisitions became routine, and 'antitakeover' followed naturally once defensive countermeasures against hostile bids developed into a distinct field of corporate strategy and law, particularly in the United States during the merger waves of the late twentieth century.
How antitakeover is actually used
Primarily a term of corporate finance, securities law, and business journalism; it appears almost exclusively in formal and professional contexts. It functions chiefly as an attributive adjective modifying nouns like 'measures', 'provisions', 'devices', 'statutes', and 'defenses', though it can also be treated as a noun phrase itself ('an antitakeover').
