difference between kind and sort

• "Kind of" means you have a kin(төрөл, гарал үүсэл) appeal(хандлага, хандаж хэлсэн үг) to the subject.
  "Sort of" means you have a assortment(нэр төрөл, ялгах, соортлох) of appeal to the subject.

• they're very similar adverbs... however," kind of" is a more formal adverb... whereas "sort of" is an informal adverb.
• In everyday usage, they're interchangeable.
• both mean the same.... but it's more used kind of

difference between sort, kind, and type

• Kind is a strang word... has double meaning.. first to describe what type of person someone is.. for example: " he is a kind man" Also to define something.. such as "what kind of clothes should i bring to china when i visit next week?".. in this case, Kind means what "type" of clothes.. the answer would be summer clothes of course. 
  
  You can substitute SORT for the word TYPE in the previous sentance.. "what sort of clothes should i take..... etc etc" the response would be the same.. Bring summer clothes. Sort and Type can also be used to ask "What sort/type/kind of person is he?" 
  
  All three words are very interchangelable.. this probably looks confusing, but the previous senantance is really all you need to know.. 

• When the reference is to the quality of something 'kind' and 'sort' are interchangeable ,while 'type' wouldn't be a substitute in that case:
  "He is kind of nice' ( sort of weird),but not 'type' of nice ,weird).
  
  When you are talking about people's qualities ,'kind' and 'type' are more applicable than 'sort'
  "He is my type' ,'he is my kind' , but not 'he is my sort'.
  
  It seems like 'type 'is more concerned with persons ,while 'sort ' refers mostly to 'things/objects'.
  'Kind' fits in both cases.

• Used as a noun, the words are interchangeable.
  "What type/sort/kind of apple is this?"
  The difference between these three words would be seen in the idioms in which they are used.
  "Out of sorts" = not feeling well
  "Sort of" = "kind of" = somewhat; you would not hear "type of" in this usage, however.
  "Of a sort" implies inferior quality.

• Very often it makes no difference which of these words we use. But good dictionaries point out some subtle differences. In fact, sometimes only one of these words is correct. For example, it would be wrong to use ‘sort’ or ‘kind’ in sentence 1 below.
  Compare these three English sentences:                                                                                         
  1. What is your blood type?
  (Expected answer is a precise named category.)
  2. What sort of prices do they charge?
  (Expected answer is a description rather than a named category.)
  3. What kind of dog is that?
  (Probable answer is a named category, but not necessarily as precise as 1 above.
  A descriptive answer is also possible.)
  So …                                                                                                                                                 
  • ‘type‘ usually means a precisely defined category.
  • ‘sort‘ is more general, often about character rather than definition and can be used in a negative way e.g.What sort of person would do a terrible thing like that?
  • ‘kind‘ is about half way between, usually referring to large categories or families of things that are naturally related.
