the verb 'tie' originates from the old english word 'tīgan', meaning "to bind or join". this old english term is derived from the proto-germanic taugijaną, which in turn finds its source in the proto-indo-european root deuk-, meaning "to lead" or "to pull". the semantic evolution from "to lead" to "to bind" is logical, as pulling something taut often secures it. the modern form 'tying' is the regular present participle/gerund formed by adding the suffix '-ing' to the base 'tie', following standard english grammatical rules for verb conjugation.
