there
The French word 'là' represents the English equivalent 'there'. It is used in pretty much the same way it would be in English, to denote a particular place or position. However, just like English, French has multiple words that can be translated as 'there', so the usage of 'là' may vary depending on the context. For instance, 'y' can also mean 'there', especially in the sense of 'in/at a place' while 'là' tends to mean 'there' in the sense of 'that place', pointing towards a certain area.
