For example, the meaning of the identical forms postale in both French and Italian is the same ('post.adj'), they share a number of collocates with the same meaning, e.g., adresse postale vs indirizzo postale, so they are likely to be well-aligned in the shared embedding space (either with or without WLD constraints).
the French form is feminine, while the Italian one is masculine, so the correct embedding space should have mapped postale in Italian with postal in French.
