The word 'permit' entered English in the fifteenth century from Latin 'permittere,' a compound of 'per-' (through, thoroughly) and 'mittere' (to send, to let go, to release). The literal meaning is 'to send through' — to allow something or someone to pass rather than blocking the way. This spatial metaphor of clearing a passage underlies all the word's subsequent senses.
Latin 'mittere' is one of the two great verb-engines of English vocabulary (the other being 'facere,' to do). Its prefixed compounds have given English an enormous family of words, all sharing the core concept of 'sending': 'admit' (send toward, let in), 'commit' (send together, entrust), 'dismiss' (send away), 'emit' (send out), 'omit' (send past, let go), 'permit' (send through, allow), 'remit' (send back), 'submit' (send under, yield), and 'transmit' (send across). The past participle 'missus' (sent) produced 'mission,' 'missile,' 'message,' and 'missive.' Together
In Classical Latin, 'permittere' had a wider and often more forceful range of meaning than modern English 'permit.' It could mean 'to let loose,' 'to hurl' (as in permitting a javelin — throwing it with full force), 'to surrender,' or 'to hand over completely.' In military contexts, when a general 'permitted' a city to his troops, he was giving them license to plunder it — a far cry from the bureaucratic mildness of a modern parking permit. The semantic softening from 'surrender, release completely' to 'allow, give permission' occurred
English 'permit' displays the characteristic noun-verb stress shift found in many Latin-derived words: the verb is stressed on the second syllable (/pərˈmɪt/ — 'to perMIT'), while the noun is stressed on the first (/ˈpɜːr.mɪt/ — 'a PERmit'). This pattern, shared with words like 'record,' 'conduct,' 'conflict,' and 'defect,' developed in English as a way to distinguish parts of speech. It has no parallel in Latin, where stress was determined by syllable weight rather than grammatical function.
The noun 'permit' — an official document authorizing something — appeared in the seventeenth century. Today, permits are ubiquitous in regulated societies: building permits, work permits, parking permits, fishing permits, export permits. The bureaucratic infrastructure of the modern state runs substantially on permits, each one a small act of authority allowing something that would otherwise be prohibited. The word thus encapsulates a particular relationship between
The related noun 'permission' (from Latin 'permissiō') entered English slightly earlier than the verb, in the fourteenth century, and retains a broader, less bureaucratic sense. One asks 'permission' (not 'a permit') to leave the table. The adjective 'permissive' acquired its modern connotation of 'excessively tolerant, especially in sexual matters' in the 1950s and 1960s, giving rise to the phrase 'the permissive society' — a term used both descriptively and pejoratively to characterize liberalized social norms.
The etymology of 'mittere' itself remains uncertain. Unlike most common Latin verbs, it cannot be confidently traced to a Proto-Indo-European root. Some scholars have suggested connections to various PIE roots, but none has achieved consensus. The verb may have been an early borrowing into Latin from another Italic language, or its PIE ancestor may have left no other surviving
In philosophy, the concept of permission has been formalized in deontic logic, the logic of obligation and permission. In this framework, 'permitted' is defined as 'not obligatory not to do' — a double negation that captures the intuition that permission is the absence of prohibition rather than a positive command. This logical structure mirrors the etymology: 'per-mittere' removes a barrier (sends it away), allowing passage through.
