Loxodrome is a line fixed at an angle with the Meridian Lines of the Earth (it is mainly Longitudinal Lines and could be extrapolated conceptually to Celestial Meridian Lines as well as for any Planet), and starts one's journey from one pole to another (mainly from South Pole to North Pole or vice versa - but it could be also taken as one East Extra mum to Western Extra mum).
Sanskrit - laKS + ah + drum -> laKS + o + DRum
LaKs -> Aim, Destination or Object of the journey, trip, path, process. Here "KS" is the compound Sanskrit Sibilant which is approximated by "X" sound in English.
ah -> Hard Aspirate, Sanskrit Visargah added to make it Nominal or Subjunctive Noun and in many cases to make it Genitive and Ablative, indicating, "of" and "from" sense. This becoms "O" when meeting Soft Vowels, and in other times, it becomes "ar", Dental "s", Palatal "sh" and Cerberal "SH" sounds.
drum -> to rum, drive away, motion, to make fluid. It can become Cerebral sounds "DR" from Dental "d" because previous "KS" as well as "r" is considered Cerebral Semi Vowel.
Note the the Musical Instrument, called "Drums" is an indication of copying by an uninitiated - as in Sanskrit, "DamRu" means the same. Because of the difficulty of Western Nations Speakers in Cerebral Sounds, and confusion with the subtlety of the sounds, there could be a tendency to say Cerebral 'D' as "DR", as well juxtaposition of the Vowel grade sound "aR" in reading Devanagari, which even my children did. The root for 'to sound' is 'Dum', and one adds Cerebral "R" to make it Agent Noun, after adding "a" by one rule, and then for making it Genitive or Ablative, it would become "DamRu-ah", and later "ah" would get dropped - meaning something "which is the agent of making the sound".
