Correct spelling for the English word "Metallical" is [mətˈalɪkə͡l], [mətˈalɪkəl], [m_ə_t_ˈa_l_ɪ_k_əl] (IPA phonetic alphabet).
Metallical is a neologism that does not have an established dictionary definition. It seems to be a derivative of the term "metallica," which refers to the American heavy metal band formed in 1981. However, "Metallical" does not directly relate to the band Metallica. In the absence of an established definition, one could attempt to interpret the term based on its structure.
The term "Metallical" could potentially be used to describe something related to or resembling the qualities of metal. Metal can refer to a strong and durable substance characterized by its high density, malleability, and thermal conductivity. It is often used to produce various objects, such as tools, weapons, or musical instruments. Hence, one could interpret "Metallical" as an adjective describing something that embodies those qualities or is reminiscent of metal itself.
Alternatively, when dissecting the term "Metallical," one could speculate that it combines the words "metal" and "musical." This interpretation could imply that Metallical relates to music genres heavily influenced by metal. It could potentially encompass a range of subgenres such as heavy metal, thrash metal, death metal, or black metal.
Overall, without further context or an established definition, the term "Metallical" remains somewhat vague and open to interpretation.
