The spelling of the word "speechmakings" may seem unusual to some, but it's actually quite straightforward if you understand the underlying sound patterns. The word is pronounced /ˈspiːtʃˌmeɪkɪŋz/, with stress on the first syllable and a final -s indicating plural. The two roots are "speech" and "making," both pronounced with the long "ee" sound. When combined, these roots form a compound noun that describes the act or process of making speeches on a particular occasion or topic.
The word "speechmakings" does not have its own separate etymology. It is formed by adding the suffix "-s" to the word "speechmaking". The etymology of "speechmaking" itself, however, traces back to the Old English word "spēc" meaning "speech" and the suffix "-maka" meaning "a maker or doer". This combination forms the verb "spēc-makian", which eventually evolved into "speechmaking" to describe the act or process of giving speeches.
