koncentrációjuk

Koncentrációjuk is a Hungarian noun phrase meaning “their concentration.” It is formed from the noun koncentráció (concentration) with the third-person plural possessive suffix -juk, indicating that the concentration belongs to a group. The word can refer to either of the two common senses of koncentráció: the chemical concentration in a solution or the mental focus and attention of a person or group. Context determines which sense is intended.

Morphology and spelling: In Hungarian, the third-person plural possessive suffix is -juk or -jük, chosen according to vowel harmony. For a stem whose last vowel is a back vowel, the form is -juk, giving koncentrációjuk. The entire construct is written as one word. This suffix marks possession without altering the base meaning of koncentráció beyond indicating ownership.

Usage notes: koncentrációjuk is used whenever it is clear that the concentration in question belongs to multiple subjects. Examples include scientific reports and observations about groups. Examples: “A mintában a koncentrációjuk 0,5 mol/L.” “A vizsgálat során a hallgatók koncentrációjukat elvesztették.” The intended meaning—chemical concentration or mental focus—depends on context and accompanying terms.
