import sys
from DictionaryServices import DCSGetTermRangeInString, DCSCopyTextDefinition

def lookup(word):
    try:
        word_range = DCSGetTermRangeInString(None, word, 0)
        defn = DCSCopyTextDefinition(None, word, word_range)
	return defn
    except IndexError:
	return 'NOT FOUND'

# Read each word from standard input, look up the definition, and print it
for word in sys.stdin:
    w = word.strip()
    if not w:
        break
    desc = lookup(w)
    print([w,desc])
