<p>Hi, i am not an english speaker. one of my recommenders is an american professor who teaches at my school this semester. he agreed to be my recommender. However, I found something very strange when he gave me the sealed and signed letter--he signed Charles instead Chuck. He told us his name is Chuck XXX in the first class and it is also Chuck on his name card. and i used Chuck for all those forms and now he signed Charles on the letter. telling me that they are the same!!!!So i want to ask you guys, the native speakers: will this bring some trouble to my application???????i am so worried.
Thank you！</p>
<p>chuck is a nickname for charles. As long as the last name matches up im sure it wont be an issue.</p>
<p>Chuck is a common nickname for Charles, similar to Bob (Robert) and Mike (Michael). Don't worry about this, no one will care.</p>
<p>Ya, don't worry about it.... there are plenty of english transitions that don't seem to make a lot of sense sometimes.</p>
<p>Let T:N->N where N is the space of english names</p>
<p>T(William)=Bill
T(James)=Jim
T(Richard)=Dick</p>
<p>T is generally one to one but certainly not onto.</p>
<p>go figure.</p>
<p>thank you all very much for your explanation! now i think i can relax:)</p>
