Biddy nodded her head thoughtfully at the fire as she took up her work again, and said she would be very particular; and Joe, still detaining his knees, said, "Ay, ay, I'll be ekervally partickler, Pip;" and then they congratulated me again, and went on to express so much wonder at the notion of my being a gentleman, that I didn't half like it.
—Dickens, Great Expectations
Where there’s stigmatization there will usually be hypercorrection. This is the origin of forms with -j- in words such as escalator and percolate. The standard ˈeskəleɪtə, ˈpɜːkəleɪt seem too plain, so people feel they would be nicer as ˈeskjəleɪtə, ˈpɜːkjəleɪt. I have marked these in LPD with a warning triangle.
Nevertheless, there are one or two words in which I have the impression that the hypercorrect form is somewhat better established.
In the hymn The Church’s One Foundation there is a verse running
’Mid toil and tribulation,The spelling of consummation (double -mm-) tells us that -j- is inappropriate in this word. So does the etymology (cognate with sum and summation, nothing to do with consume). Yet I think congregations rather often sing ˌkɒnsjuˈmeɪʃən rather than ˌkɒnsəˈmeɪʃən or ˌkɒnsʌˈmeɪʃən. Perhaps the adjacent tribulation pushes one in that direction, too.
And tumult of her war,
She waits the consummation
Of peace forevermore;
Till, with the vision glorious,
Her longing eyes are blest,
And the great Church victorious
Shall be the Church at rest.
In LPD, accordingly, I have placed no warning triangle for -j- in consummate, consummation. Ought I to have?
