The spelling of the word "Dilling" can be confusing as it does not follow the usual conventions of English spelling. In IPA phonetic transcription, the word is spelled /dɪlɪŋ/, with emphasis on the first syllable. The "d" is pronounced as a voiced dental plosive, the "i" as a short vowel, and the double "l" as a voiced alveolar lateral approximant. The final "ing" indicates a present participle form. Therefore, "Dilling" refers to something that is currently happening or ongoing.
A darling or favourite; the youngest child; the youngest of a brood.
