The simple English word "by" - like many other prepositions - covers multiple grammatical functions, which makes it hard to translate into Thai. The Thai language uses different words for the different functions, so we will go through each function in detail:
  • means - I did it by hand
  • means of transportation - I travel by bus
  • place - a house by the sea
  • time - read it by tomorrow

By in Thai: means

To express the means using "by" in Thai, you use the same concept as the preposition "with". For example, "I did it by hand" in Thai is equal to "I did it with my hands". For this we use the following patterns:
  • [subject] + [verb] + [object] + ด้วย + instrument
  • [subject] + ใช้ + instrument + [verb] + [object]
You can also look at the article With in Thai, to find out more.

ฉัน ซ่อม รถ ด้วย มือ
Literally: I - repair - car - with - soap

By in Thai: means of transport

Traveling by vehicle is often expressed as:
  • นั่ง /ขับ /ขี่ [vehicle] ไป /มา [location]
    Literally: sit/drive/ride - [vehicle] - go to / come from - [location]
นั่ง is used as a passenger, e.g. on a bus, plane or in a car, ขับ is used when you drive a car, and นั่ง is used on a motorcycle.

But when you don't indicate the vehicle type, you use ด้วย , e.g. I flew to Thailand with Thai Airways
