By now you may have discovered that there are many more words "hidden" in these examples. Take one
of the previous examples, the English word "Neutrality": by removing the ending, you end up with the word
"Neutral". In many cases, it works for the Spanish translation as well: remove the ending ...idad and you
have the word "Neutral", which is the proper Spanish translation!
Sensuality without the ending is Sensual; Sensualidad without the ending is Sensual. You learned in
Chapter Six that English words ending in...al are the same in Spanish!
Some words such as "Tranquility" (Tranquil) are almost the same in Spanish. "Tranquil", in Spanish, is
"Tranquilo"; "Solemnity" (Solemn) is solemnidad (Solemno)!
