haematological

The word 'haematological' is a modern scientific term constructed from classical Greek components. Its foundation is the Greek root haimat-, meaning "blood", which can be traced back to the Proto-Indo-European root sai-, meaning "thick liquid, blood". This root is combined with -logia, from Greek logos (word, discourse, reason), which in scientific terminology denotes a field of study. The connecting vowel -o- and the adjectival suffix -ical are added to form the complete adjective. Thus, the term's literal construction, "relating to the discourse/study of blood", directly and logically yields its modern meaning pertaining to the scientific study of blood and its disorders.
