If you want to know how a word is written in contracted braille, check the accurate and easy-to-use BRL: Contraction Lookup Dictionary!
From the website:
"This is a simple program to provide you with the proper contraction for a given word. To use the program, simply enter your word into the text box, click on the "Get contraction" button, and wait until the contraction appears. If the contraction is not in the dictionary (containing over 45,000 words), you will get a message telling you that it is not available! If the word is not in the dictionary, or near the end of the alphabet, the program will take a little longer to run! The dictionary is case-sensitive!"
