'insufficiently-verified' originates from the combination of 'insufficiently' and 'verified'. 'Insufficiently' comes from Latin 'insufficientem', meaning 'not enough', and 'verified' comes from Latin 'verificare', meaning 'to make true'.

'Insufficiently-verified' evolved from the combination of 'insufficiently' and 'verified', which were used separately in Middle English and later combined in modern English.

Initially, 'insufficiently' meant 'not enough', and 'verified' meant 'to make true'. Together, they evolved to mean 'not adequately confirmed'.
