To make clearer the following analysis of Kfarsghab etymology to the non specialist reader, here's an excerpt taken from A Glimpse of Yesterday, A Typology of Regional Variation and Cultural Continuity in Lebanese Place-Names by Elie Wardini, Department of East European and Oriental Studies University of Oslo :

As far as semantics are concerned Wild states: "Place-names show the Lebanon as a resort of the pious, where Canaanite gods, Christian saints and Muslim sheikhs mingle. Valleys and rivers, springs and forests, peaks and mountains stamp the life of the people. Place-names, the linguistically petrified remnants of cultural history, preserve the memory of the cedar, where there are no more cedars, and recall roaming wolves and bears where there are no more than the occasional fox. Generations of hunters and farmers, shepherds and hermits have left their unmistakable imprint on Lebanese toponymy."

As far as structure is concerned Lebanese place-names are structurally of two kinds: i) simplex (usually a noun), ii) Ncst + NP (the first Noun in the construct state and the NP can be a place-name, a personal name or a noun). As far as languages are concerned I expect to find the following:

i. Canaanite unchanged place-names (e.g. Be'erot = Beirut, Sur = Tyre).

ii. Aramaic unadapted names (e.g. Bikfayya, Kifrayya)

iii. Adapted Canaanite/ Aramaic names through:

a) translation: (Canaanite Sidon > Aramaic Sayda "fishing, hunting"; unattested pre-Arabic "house of youth" > attested Arabic Bayt Shabeb

b) phonetic changes: (*Bashkinta > Baskinta "the house of dwelling", following the regular correspondence between Aramaic /sh/ and Arabic /s/)

c) folk etymologies: (*NaHla "valley" > Nakhle "palm-tree" due to frequent correspondence between Aram/aic /H/ and Arabic /kh/)

iv. Arabic names (M'amiltayn "the two districts") evenly spread in Lebanon

v. Non-Semitic names (Turkish Qashlaq "winter quarters"; French Bois de Boulogne; Greek InTilyes < antelios "the sun offering")
