Friday Ramble - Aestival

In the science of zoology, aestival refers to the tendency of all living creatures to be sleepy and slow moving in the heat of summer, and botanists also use the word to describe the arrangement of organs or components in a flower bud.

This week's word comes to us from the Late Latin aestīvālis and earlier Latin aestās, both meaning summer or heat. Both forms are cognate with the Sanskrit इन्द्धे (inddhé) meaning to light or set on fire. At the end of our wordy explorations is the Proto-Indo-European (PIE) root form h₂eydʰ- meaning heat, fire or to burn. The adjective probably came into use during the Middle Ages, some time around 386. 

Proto-Indo-European (PIE) is the reconstructed common ancestor of nearly all Indo-European languages and its elements have been assembled from those known today. There is no record that it ever existed, but if so, it would have been in use from the Late Neolithic to the Early Bronze Age. The prehistoric Proto-Indo-Europeans were most likely nomadic tribes from the steppes of eastern Europe and central Asia. They were a footloose and fancy free lot. There is evidence that they wandered as far as the Aegean, northern Europe, Central Asia and Siberia, leaving their language, religious beliefs and customs wherever they went.

I once thought that the word siesta (referring to a leisurely nap after lunch) was related, but I discovered a year or two ago that its roots are in the Latin sexta meaning the sixth hour of the day (midday). The two words sound similar, but as far as I know, they are not related.

This week's word is my favorite adjective for the (all too brief) greening season at the heart of the calendar year. Summery is a fine word too, but it doesn't hold a candle or even a tiny wooden match to the frothy perfumed magnificence of the golden season that reigns so gloriously and so briefly here in the sub-Arctic climes of Canada. Aestival says it all, and I love the shape of the word on my tongue.

I say "aestival" and its sibilance summons up images of alfresco celebrations and farmers' markets, shaggy gardens of scarlet poppies and towering purple lupins, trees filled with singing birds, bees in the orchard, roses sweeter than any vineyard potion, perfect sunsets across the lake shared with herons and loons. The season is filled with light, and every moment should be savoured.
