elektrickém

Elektrickým is the instrumental singular form of the Czech adjective elektrický, meaning electric. In Czech, adjectives agree with the nouns they modify in gender, number, and case. The instrumental singular form is used to express means, manner, or instrument, and it appears as elektrickým for masculine and neuter nouns, while feminine nouns typically take elektrickou.

Typical uses include phrases such as by means of electricity or with electrical equipment. Examples: elektrickým proudem (by electric current), elektrickým nástrojem (with an electric tool), or elektrickou energií (with electric energy). These constructions are common in technical, scientific, and everyday language when describing how something is powered, controlled, or performed.

Etymology traces elektrický to the word elektrika (electricity), itself derived from the concept of electricity and ultimately from the Greek elektron through Latin and other European languages. The form elektrickým reflects standard Czech adjective inflection patterns in the instrumental masculine and neuter, allowing it to modify nouns in contexts involving means or instrumentality. The feminine instrumental form is elektrickou.

In usage, elektrický and its inflected forms like elektrickým are frequent in technical texts, product specifications, engineering discussions, and descriptions of electrical phenomena. They contrast with related terms such as elektřinou (using the noun electricity in instrumental form) and electronic equivalents like elektronický, which pertains to electronics rather than general electricity.
