cambar m. [ˈkʰãũmb̥əɾ], 
AFB˄: /kãũmbər/.
Final SG -[ɾ] in unstressed syllables is frequently palatalised in the dialects of the Western Isles, cf. SGDS Items 670 piuthar (Pts 6–7, 14–19, 28–30), 730 saighdear (Pts 1–5, 7– 13, 17–30), 851/2 tobar (Pts 1–9, 25, 17–18, 28–30).
A. Bernera, Harris
‘[A]bout a hundred yards from [the former church] Cill Àisinn is An Cambar, a burial ground still in use ... Some knolls nearby are called Na Cambair Bheaga “the little mounds”’ (≈CG VI, 30). OS 1843–82 gives Cill Aiseam NF928826 with its own graveyard immediately beside it; another burial ground is located at NF932828, about 490m (1600ft) from Cill Aiseam. For An Cambar, cf. the place-names (OS 1843–82) Allt Camber NF931826, Port a’ Camber NF934822 and Massacamber NF939826, which are presumably anglicised forms of SG (with or without the article) Allt (a’) Chambair, Port (a’) Chambair and Màs (a’) Chambair ‘the stream—, the landing-place— and the base of (the) Cambar’, although MacGillEathain’s (1988, 39) form Port a’ Chambair and AFB˄’s Màs a’ Chambair confirm use of the article.
B. St Kilda
Carmichael (≈ibid.) writes ‘[a] burial place in St Kilda is also called An Cambar; its situation is ... above the stormy exposed bay of the island’, appending the rhyme (which he says is known elsewhere, in the islands and on the mainland): Tobar Childa Chalda | Allta Chamar nan Lobhar ‘the well of—, 
For Carmichael’s Tobar Childa Chalda, see Cox 2007c, 21–22; 2022, 579–80 fn 207.
Martin Martin (1698, 116–17) says that leprosy broke out among the population of St Kilda c. 1684, and that there were current cases during his own visit to the island. This leprosy was probably lepra tuberculosa, according to MacDonald (1886, 161).
In addition to Tou-bir-nimbeuy (SG Tobar nam Buaidh ‘the well of the virtues’), Martin Martin (1698, 87–88) mentions St Kilder’s well (i.e. Carmichael’s Tobar Childa Chalda) and ‘another well within half a mile of [the main village], named after one Conirdan, an hundred paces above the sea’; of these wells, Macaulay (1764, 93) notes that ‘the most remarkable is that near the Camper’. Whether or not Conirdan is or contains an adulterated form of cambar or similar is impossible to determine. (Macaulay translates (p. 28) Camper as ‘the crooked landing-place’, (p. 93) the Camper as ‘crooked bay’, presumably on the basis of SG cam ‘bent, crooked’; the name is given as the Campar on p. 118.)
John Matheson’s 1928 map of St Kilda includes The Cambir and Geo Chaimbir.
C. Ness, Lewis
Carmichael (≈ibid.) continues, ‘[t]here is a place in Ness, Lewis, called An Cambar: air a’ Chambar ‘at Cambar’; an old Lewis song says, ‘Chì mi uam an Cambar thallad “I can see An Cambar yonder” ’, although the traditional spelling is with -mp- rather than -mb-, 
E.g. àirigh a’ Champair lit. ‘the sheiling of An Campar’ (Mac-an-Rabhd 1954, 178).
With SG mòr ‘large’ and beag ‘little’, respectively, but onomastically here in the sense ‘greater’ and ‘lesser’.
On the basis that SG cambar goes back in some capacity to ON kambr in the sense ‘comb or crest (of hills)’, the term appears to denote, in Bernera, the two hills (OS 1843–82: Sand Hill and Moor Hill) to the north-east and north of the map’s Allt Camber; in St Kilda, the series of steep crags forming a long promontory crest or ridge running north-west from NA081000 to NA075011; and, in Ness, the series of low hills forming a crest or ridge running north-west from NB538594. (Carmichael’s sense ‘burial mound’ may be the result of transference of onomastic meaning (Cox 2002a, 45–46; 2022, 33–36) or his own interpretation.) A number of scenarios have been or might be considered:
1. SG cambar is a loan-word from ON kambr. As mentioned above, this is Angus Matheson’s view; it is also MacIver’s (1934, 46–47, 74 
(Bernera) massa-camber < ON cambr [sic], Port a chamber < ON kamber [sic] and (Ness) Campar from ON kambr.
McDonald conflates cambar with SG camp ‘overhang’ (s.v.) and campar ‘hindrance, annoyance etc.’ (s.v.).
2. Taylor (1968, 126) seems to imply that the St Kilda place-name The Cambir [sic] is derived from an Old Norse place-name *Kambr; even if this were likely to be the case, the same questions would apply as under (1.).
3. SG cambar is a loan-word from ON kambar ‘(the) hills’, pl. of kambr, used in Gaelic as a grammatically singular or collective appellative, but there do not seem to be any other examples of such a development, especially one occurring across several islands.
4. SG cambar goes back to *campbheur, consisting of SG camp, a loan-word from ON kamp, acc. of kampr m. ‘overhang’ (s.v. camp) + SG beur ‘point, pinnacle’, as suggested by Coates (1990, 115) for St Kilda.
Coates opines that the usual current English form, (The) Cambir, suggests a Gaelic *An Caimbir, but this is not supported by Gaelic usage.
In support, Coates cites the (North Tolsta, Lewis) place-name Sròn a’ Champair NB563473 (cf. OS 1843–82 idem, Geodha Champair NB562472 and Sgeir a Champair NB562473 ‘the promontory, cove and skerry of the—’), but this is for Srò(i)n a’ Chambair: SSSA PN1967-002-SideA, from approx. 13.30 minutes: [̩ ̩s̪ɾõˑɲ ə ˈxãumb̥əɾʲ]. MacIver (1934, 16) writes Sròn a Champair, but derives the specific from ON kambr. Cf. OS 1843–82 Lòn a’ Champair NG444582 ‘the pool of the—’ in Skye, although the pronunciation is unknown. (The Old Norse loan-name SG Campaigh [ˈkʰãũm̥paj] NB142426 probably derives from ON *Kamp-ø̨y ‘(the) overhang-island’, with the stem-form of ON kampr, s.v. camp (Cox 2002a, 198). Macaulay (1972, 330), possibly on the suggestion of Hermann Pálsson (p. 329), gives a derivation with ON kamb- ‘comb, crest’, but this does not seem to suit phonetically.)
A nominal use of SG beur, a by-form of bèarr, beàrr (EG berr ‘short’) (MacBain 1911).
5. SG cambar is a loan-blend of ON kamb acc., or Scots (Shetland) kamb ‘a sharp-crested mountain ridge (now only as a place-name)’ (< ON kambr) (Jakobsen 1928; 1936, 64; SND˄, s.v. kame), + the Scottish Gaelic collective suffix -ar -[əɾ] (Thurneysen 1975, 170 §265 (a)), cf. SG Crochar ‘place of the gallows’ in Urquhart, Salachar ‘place of willows’ (-[aɾ]) in Applecross (Watson 1904, xxxvii, 117, 205), glasar ‘green place’ and (plur.) gleadhairean ‘slopes’, iolairean ‘ledges’ and gortairean ‘enclosures’ in Lewis (Cox 2002a, 60).
The first and last scenarios (1. and 5.) seem the most likely, with the principle of Occum’s razor favouring the former.
MacIver (1934, 23) lists Tom a Chamba [sic] in Borve, Lewis, whose specific he derives from ON kambr, but we should probably read *Tom a’ Chama, cf. (Borve) OS 1843–82 Càm, ECC 283 An Camadh NB44805213, also (North Tolsta) OS 1843–82 Camadh NB544473, both locations with a stream in a steep gully, although MacIver (ibid., 16) gives the latter as A Chamach [sic], which he also derives from ON kambr; but such names may simply contain SG camadh in the sense ‘bow, curve’ and/or camach ‘bowed or curved place’ (< SG cam ‘bent’).
