Morphology

ultrahigh = high (transparent) = ultra + high

The word is a straightforward prefixation of 'ultra-' to 'high', yielding the meaning 'extremely high'.

Etymology

Ultrahigh combines the prefix ultra- meaning 'beyond' or 'extremely' and the word high, so it means 'beyond high' — in other words very or extremely high in level, value, or degree.
