WHY A UNIALPHABET SYSTEM OF CLASSIFICATION

Bilingual dictionaries come in two parts, Spanish and English. They should overlap, but they don´t, and that is why I "invented" the unialphabet system: one dictionary with both languages together, making the search easier and the vetting less complicated. For example: I search for "when push comes to shove" in the online Collins Spanis-English dictionary and I get "a la hora de la verdad" which does not appear under "hora" or "verdad". A Spanish speaker would never come across "when push comes to shove" unless chance lends a hand. Check your bilingual dictionary and you will often find discrepancies in the two parts. Spoiler: the different teams of lexicographers are not in touch and don't even know one another.
