Hortative modalities share semantic and lexical similarities with other modalities, which can lead to confusion between them. Also, hortative constructions rarely have forms that are uniquely their own. The
English expression '''Let's
, a contraction of let us
, is one such construction. However, let us''' is used for other functions: • Andy says to his sister Barbara: "The movie starts in an hour. '''Let's go.'''" Andy is telling Barbara that they should leave now if they want to make it to the movie on time. (cohortative – mutual encouragement) • Barbara says to her parent, Chris, "We have finished our chores.
Let us go." Barbara is demanding that Chris allow them to go to the movies because they have no more chores to do. (
imperative) The modal '(have) got' is used to express obligations, but is also hortative: • Chris says to their employee, Ethan, "Donna is out sick today. '''You've got to be there'''." Chris is telling Ethan that because his co-worker is sick, he must come to work. (
obligatory – being there is required) • Ethan says to his friend Frankie, "It's gonna be the biggest party of the year. '''You've got to be there'''." Ethan is telling Frankie that she should go to the party because it will be the biggest of the year. (exhortative – being there is strongly encouraged) Further ambiguity may result when hortative formations have many words or appear as adverbially-modified forms of other modalities: • Frankie says to her friend Greg, "Recently, some cars have been broken into.
You might not want to park there." Frankie is cautioning Greg against parking where some cars have recently been broken into. (dehortative – parking there is politely discouraged) That construction consists of might (a modal of possibility) + not (the negative marker) + want (a
volitive lexical
modal). Forms such as this one are often misconstrued as other modalities further modified (in this case, volition negated and modified for possibility). == Imperative-hortative systems ==
