"Do you come here often?"

Translation: Chodíš sem často?

What is the difference between sem and tacy?

[endless_sleeper]

sem = here, to here, hither => direction

tady = here, at this place => location

tácy is the plural of tác = platter, tray

[Peter473545]

Then tady should certainly be accepted. When you say "do you come here?", you are usually asking if they come to this location, not if they come in this direction.

[VladaFu]

"to this location" is a direction, the key is in the "to"

Observe the difference between where and whither, beween here and hither, between there and thither, between elsewhere and elsewhither. Those are the differences between a location and a direction. It is not foreign to English, just a bit archaic.

See this comparison and consider the distinction in Czech similar to what was in English around year 1600, but completely strict.

Why is "přijdeš sem často?" not accepted?

[VladaFu]

Přijdeš is for one comming in the future, not for habitual comming. For example, "Přijdeš sem brzo?" "Will you come here soon?"

[DavidMills574753]

I just wondered why jdeš or jedeš are not acceptable here? Is it because of a connotation chodíš to regularity? Thanks
