We have used optical spectroscopy to probe the normal state electrodynamicresponse of Fe$_{1.06}$Te$_{0.88}$S$_{0.14}$, a member of the 11 family ofiron-based superconductors with T$_c$= 8 K. Measurements have been conductedover a wide frequency range (50 - 50000 cm$^{-1}$) at selected temperaturesbetween 10 and 300 K. At low temperatures the material behaves as an"incoherent metal": a Drude-like peak is absent from the optical conductivity,and all optical functions reveal that quasiparticles are not well defined downto the lowest measured temperature. We introduce "generalized spectral weight"analysis and use it to track temperature induced redistribution of spectralweight. Our results, combined with previous reports, indicate that the 11family of iron-based superconductors might be different from other families.
