These second persons singular of verbs
Are far too tricky; once involved in these,
For instance, "lovedst" and "spreadst" and "stillst" and "gapest,"
And thousands more—once, as I say, involved
In these too clinging tendrils one is done;
And so I find I cannot write an ode,
Not even a ten-syllabic blank-verse ode,
In second persons singular of verbs,
In "snifflest" and in "wheezest" and the rest,
For I am sure to trip and spoil the thing,
