• Synonyms and Trespass upon, Encroach upon, Intrench upon, Trench upon, Infringe upon, Intrude upon, Transgress. Trespass upon, though figurative, expresses generally the idea common to these words, that of unauthorized, improper, or undesirable coming upon ground not one's own. The order is essentially that of strength, and there is a corresponding increase in the presumption that the offense is committed knowingly. To trespass upon another's rights is literally to step or pass across the line of demarcation between his rights and ours. To encroach upon anything is to creep upon it to some extent, and often implies moving by stealth or by imperceptible degrees and occupying or keeping what one thus takes: the ocean may thus be said to encroach upon the land by wearing it away. To intrench upon, or latterly more often trench upon, is to cut into as a trench is lengthened or widened; it does not especially suggest, as does enroach upon, either slowness or stealth. Infringe or infringe upon means a breaking into; hence it is a much stronger word than those that precede it. Transgress is stronger and plainer still, meaning to walk across the boundary, as of another's rights. Intrude upon suggests especially that one is unwelcome, and goes where regard for others' rights, as of privacy, or the sense of shame, should forbid him to press in.
