Etymology
The verb 'let' originates from the Old English 'lǣtan', meaning 'to allow, permit, leave behind, or bequeath'. This term is derived from the Proto-Germanic 'lētaną', which carried a similar sense of allowing or leaving. The Proto-Germanic root can be traced further back to the Proto-Indo-European 'lēd-', meaning 'to let go, release'. An interesting semantic evolution occurred where the original sense of 'allow' was preserved in English, while in other Germanic languages, the root often developed a meaning related to 'hindrance' (as seen in German 'verletzen', to injure). The modern English usage for renting property emerged in the Old English period, stemming from the idea of 'allowing' someone to use land or dwellings.
