What does contentious mean?
Contentious describes something likely to provoke disagreement, debate, or conflict — a topic on which people hold firmly opposing views. A contentious issue, such as tax reform or land use, is one that reliably generates argument whenever raised. The word derives from the Latin contendere, meaning to strive or struggle, and carries that sense of active friction. While primarily used of subjects and questions, it can also characterise people as quarrelsome or inclined to argue, which lends the word a mildly negative edge in that context. In law, contentious has a specialised sense: it describes matters involving genuine dispute between parties, as in contentious litigation or contentious probate, as opposed to routine, uncontested proceedings. Common throughout British and American English, particularly in political and journalistic writing, contentious is a precise way to flag that a topic divides opinion and should be handled with care.
Likely to cause disagreement or heated debate; controversial.

(Law) Involving a dispute between opposing parties, as opposed to an uncontested or non-adversarial matter.

Contentious shares its Latin root with 'tennis' — both trace back to tenere, 'to hold,' because players once held (tenerez) the ball before serving.

Etymology of contentious
Contentious comes from the Latin contentiosus, derived from contendere, meaning 'to strive, contend, or compete' — itself formed from com- ('together') and tendere ('to stretch'). It entered English in the early 15th century, initially carrying senses related to striving or quarrelsomeness before settling into its modern sense of provoking dispute. It shares its root with words like contend, contention, and tenacious, all ultimately tracing back to the Latin verb tenere, 'to hold.'
