Cross sections, angular distributions and forward-backward asymmetries are presented, of two-fermion events produced in e(+)e(-) collisions at centre-of-mass energies from 189 to 209 GeV at LEP, measured with the ALEPH detector. Results for e(+)e(-), mu(+)mu(-), tau(+)tau(-), q (q) over bar, b (b) over bar and c (c) over bar production are in agreement with the standard model predictions. Constraints are set on scenarios of new physics such as four-fermion contact interactions, leptoquarks, Z' bosons, TeV-scale quantum gravity and R-parity violating squarks and sneutrinos.
