Synonym discussion
Sense: noun/1
All four words describe a failure to show thanks, but they differ in register and focus. 'Ungratefulness' (B2) is the most direct and commonly used in everyday situations — it sounds natural when describing someone's behaviour towards family, friends, or colleagues. 'Ingratitude' (C1) comes from Latin and carries a more formal, literary, or moral weight; you are more likely to find it in essays, religious texts, or philosophical discussions ('the sin of ingratitude'). 'Thanklessness' is less frequent and often describes the quality of a task or situation rather than a person — for example, 'the thanklessness of the job'. 'Unappreciativeness' focuses on failing to recognise the value or effort of something, and is the least common of the four. If you want to say that a friend did not thank you for a gift, 'ungratefulness' is the best choice. If you are writing about a character flaw in a novel, 'ingratitude' may fit better.

Etymology
Formed in English by adding the suffix '-ness' (which turns adjectives into nouns) to 'ungrateful'. The word 'ungrateful' itself combines the Old English prefix 'un-' (meaning 'not') with 'grateful', which comes from the Latin 'gratus' (meaning 'pleasing, thankful'). The core sense of not feeling or showing thanks has remained stable since the word first appeared in English in the 16th century.
