Morphology

lymphocytosis = lymphocyte (transparent) = lymph + cyte + osis

Standard medical formation: 'lymphocyte' + the suffix '-osis' denotes a condition or abnormal increase relating to lymphocytes.

Etymology

Lymphocytosis comes from three parts: lymph meaning 'a clear body fluid', cyte meaning 'cell' (the same idea as the common word 'cell'), and -osis meaning 'a condition' or often 'an increase' in medical words. So, lymphocytosis literally means a 'condition of lymph cells', which explains why it describes an increase in lymphocytes in the blood.
