"We live here."
Translation:Ni loĝas tie ĉi.
I found this table to be very helpful. https://en.m.wikibooks.org/wiki/Esperanto/Appendix/Table_of_correlatives
rfeuand gave a nice answer above. Here it is again, (but with the Ĉ/ĉ characters):
The "ti" part of tie means "that."
The "e" part of tie means "place."
(See the table of correlatives someone recommends below.)
Ĉi expresses close proximity. So...
tie = that place = there
tie ĉi = that place near me = here
