gen. campair -[æɾʲ], -[ɛɾʲ], in the sense ‘hindrance, annoyance’ is derived by Mackay (1897, 92) from Ice. kampr ‘crest or front wall’ (ON kampr).
McDonald (2009, 369) conflates campar with SG cambar ‘crest’ (s.v.) and camp ‘overhang’ (s.v.).
In addition to Mackay’s ‘hindrance’, SG campar has the senses ‘anger,

However, MacBain (1896; 1911) and Henderson (1896 II, 327, 330) derive SG campar from Scots cummer (MacBain: cummar), also cumber, ‘hindrance; action of troubling, disturbing or embarassing; quarrelling etc.’ (SND˄).
HSS 1828 gives a folk etymological derivation from SG cam ‘crooked, bent’ + tuar ?‘hardship’; so also MacLeod and Dewar 1833.
MacLennan (1925) suggests campar goes back to EG campar ‘contention, quarrel’, but this seems to be a conflation of SG campar and EG caimpear, campar ‘warrior, champion’, a derivative of EG cám (Vendryes 1996: caimper, campar), s.v. caparaid: SG campur ‘champion’ is listed in Shaw 1780, but seems either to have been already obsolescent or to have been adopted from Irish.
Cf. O’Clery 1643: caimpear ‘champion’; Lhuyd 1707: †caimpear ‘idem’; O’Reilly 1817: caimpear ‘idem’; Dinneen 1947: idem ‘warrior’; Ó Dónaill 1977: idem ‘champion’. O’Reilly lists campar ‘grief, vexation’ and camparach ‘vexatious, grievous, troublesome’, but these seem to have been adopted from Scottish Gaelic.
The Scots etymon is likely to have been cumber, unless the medial plosive in Gaelic was intrusive, cf. SG slaman ‘curds’ (< EG slamm), (Islay) slamban (McAlpine 1832; cf. Calder 1972, 66); it is just possible, of course, that campar with medial [m̥p] (as opposed to [mb̥]) was influenced by an obsolescent campar ‘champion’ (Shaw’s campur), assuming the latter is not a ghost word.
Derivatives: SG camparach ‘angry, vexatious, grievous, troublesome etc.’, with the adjectival suffix -ach; camparachd f. ‘vexation, grief etc.’, with the abstract noun suffix -achd; and seemingly camparaid ‘bustle’ (Dwelly 1911), ‘bustle, a slight quarrel’ (MacLennan 1925), for whose ending s.v. caparaid fn 2.
