What does alchemistical mean?
"Alchemistical" is an adjective describing anything connected with alchemy, the medieval blend of philosophy, proto-chemistry, and mysticism whose practitioners sought to turn lead into gold and discover an elixir of life. In practice it functions as a rarer synonym of "alchemical," the form modern writers overwhelmingly prefer. The word appears most often in historical, literary, or academic contexts — describing old manuscripts, engravings, furnaces, or treatises dense with cryptic symbolism — and it can also be used figuratively to suggest a seemingly magical transformation, as when a cook's improvisation is called alchemistical. Its connotations are those of secrecy, arcane learning, and half-scientific wonder, which makes it useful when a writer wants to evoke atmosphere rather than mere description. Because it is uncommon and slightly old-fashioned, readers may find it striking but should recognize that choosing "alchemical" would sound more natural in contemporary English.
Relating to alchemy or its practices, writings, and symbolic apparatus.
"The library's rare-books room held several alchemistical treatises bound in cracked leather."
Prefer "alchemical" in ordinary modern writing; reserve this form for historical or deliberately archaic register.
(Figurative) Evoking mysterious or seemingly magical transformation, by analogy with the aims of alchemy.
"His alchemistical talent for negotiation turned a hostile meeting into a partnership."
It's the longer, fussier cousin of "alchemical" — the word writers reach for when they want their magic to sound extra scholarly.

Etymology of alchemistical
The word descends from "alchemy," which entered medieval Latin as "alchimia" from Arabic "al-kīmiyāʾ," the article "al-" giving the term its distinctive opening. The Arabic itself is usually traced back to Greek "khēmeia" (or a related Egyptian-derived root), making the word a meeting point of Greek, Arabic, and Latin learning. English formed "alchemistical" by adding the adjectival suffix "-al" plus "-istic" to the noun stem, producing a fuller variant alongside the simpler "alchemical." Its closest relatives are the other words built on the same stem — "alchemist," "alchemy," and "alchemical" — while its broader cognates include "chemistry" and "chemical," which share the ultimate Greek source.
