I use lingusitics many times for example
1. As said konda related andhra
2. Alai related to tamil nadu ---- mudumalai , megathmalai etc
3. Kulam related to malaylam (kerala ) ---- eravikulam , paravikulam etc
3. Atta related to karanataka --- goyembattaa
And others , I am not able to remember , but we can use our common sense here , it can fetch marks , for example in Buddhism linguistics can be used effectively words like thera , theri , madhyamika etc can be linked to Buddhism .
It can be used but sometimes it backfires also , that thing can be avoided by avoiding wild guesses , if something is connecting linguisticly than we can apply this but on own your that this world can be related to some region that can cause more negative , our brain works in patterns , when ever I read things which are factual I connect them daily life things in. Some other way possible , either linguistic or act or place or thing. May be do not get exactly while solving , but the patterns remains in mind and your common sense will tell you ohk this is most probable answer .
