interloperyoudaoicibaDictYouDict[interloper 词源字典]
interloper: [16] An interloper is literally someone who ‘runs between’. The word was coined in English, but based on Dutch loper, a derivative of lopen ‘run’ (to which English leap is related). It originally denoted someone who engaged in trade without authorization, and only in the 17th century took on its present-day meaning ‘interfering outsider’.

occuryoudaoicibaDictYouDict
occur: [16] Etymologically, occur means ‘run towards’. It was borrowed from Latin occurrere, a compound verb formed from the prefix ob- ‘towards’ and currere ‘run’ (source of English course, current, etc). This had the sense ‘run to meet’, hence simply ‘meet’, which survived into English: ‘The whole multitude might freely move … with very little occurring or interfering’, Richard Bentley, Boyle Lectures 1692. But ‘meeting’ also passed into ‘presenting itself’, ‘appearing’, and hence ‘happening’ – from which the main present-day meaning of English occur comes.

tamper: [16] Tamper began life as a variant of temper. It originally meant ‘mix clay together with water to make it suitable for use’. However, the notion of ‘mixing’ seems to lead on naturally to ‘interference’ (meddle originally meant ‘mix’), and by the end of the 16th century we find that ‘tampering with clay’ had moved on to ‘tampering with anything’ – ‘interfering’ with it.
