In the dictionary I found: to lack smth, but in the example there is a preposition: We lack <b>for</b> nothing, thank you.<br/><br/>I also heard: our team <b>lacks</b> the appropriate talent to complete this project. (no preposition)<br/><br/>So, is there any difference between these two cases? Or maybe both variants are possible for <b>lack</b> as a verb without change in meaning?
