nekoncentrují

Nekoncentrují is a Czech word that translates to "they do not concentrate" or "they are not concentrating" in English. It is the third-person plural imperfective present tense form of the verb "nekoncentrovat" (to not concentrate). This verb indicates a state of being unfocused or lacking attention.

The word can be used in various contexts to describe a lack of mental focus. For instance, one might say "Studenti se nekoncentrují na hodinu" meaning "The students are not concentrating on the lesson." Similarly, it could describe a general inability to focus on a task, such as "Děti se v tomto věku často nekoncentrují dlouho" which translates to "Children at this age often do not concentrate for long." The imperfective aspect of the verb implies an ongoing or habitual lack of concentration, rather than a single, completed instance. The meaning is context-dependent, but always relates to a deficiency in applied mental effort or attention.
