PREFACE (Bro. Surakit Srisrankulwong, Ph.D.) Director March 2023 Nowadays, learning English is the most essential activity in our daily routine. Needless to say, it is the most fundamental means of communication in the field of education in order to instill in the learner’s positive attitudes towards English language. Consequently, the learner can use the language in multiple life situations, and in search for knowledge to sustain a career and further high level of studies. In addition, it can also aid the ability to understand various cultural differences and challenges. Therefore, the teaching and learning process is considered to be most beneficial as the teacher educates the subject content thus enabling the learner to grasp in a less complex effort. This vocabulary book is published for the exclusive use in teaching and learning of five basic subjects namely Mathematics, Science, Technology and Occupation, Social Studies, Religion and Culture and English for Primary 1 to Secondary 6 students. This book introduces English vocabulary words used in the abovementioned subjects with examples on how to adapt them in daily communication to attain goals and efficiency. It is with great expectation that the contents in this English vocabulary book may benefit the teachers and students in a way that it is genuinely learned as English is a medium of instruction. Every single vocabulary word is related to the learner’s daily life. The contents are expected to respond to the basic learning needs and preferences of the learner and therefore may involve recreational learning and utmost advantage. Finally, I would like to acknowledge the valuable efforts of the teachers of the Foreign Languages Department, the Academic Affairs, and those who in one way or another have been part of the preparation and success of this book. God bless you constantly.

4 SAINT GABRIEL’S COLLEGE, THAILAND COAT OF ARMS Coat of arms is a translation of the French COTTE D’ ARMES. Usually it is depicted with the particular heraldic bearings of a person or family on an escutcheon, and from it we can learn much about the person or family which adopted the particular coat of arms. BROTHERS OF ST. GABRIEL The name “the Brothers of St. Gabriel” reminds us of those Brothers who sacrificed their lives, and their mother’s land, in order to help educate and develop our Thai children to grow in the right path. “LABOR OMNIA VINCIT” is the motto of our school. “We can overcome all difficulties through working hard,” or, as the Latin proverb says : “Labor conquers all things.” “Life - Boat” Symbolized By “The Ship in The Sea” “The ship in the Sea” symbolizes that we have to keep on struggling and facing different difficulties in the sea of life, just like the ship or the boat that fights stormy wing, steamy sun and rainy sea in order NOT to capsize in the middle of the sea. This should always remind us that “Life is a Struggle” or “To Live is to Struggle” against the problems and difficulties and not to give up. “DS” (read “D and S”) Cross In The Middle With The Cross “D” or Divinity represents “Religion”. We all need religion in life and mind. The Cross is the symbol of “love” and “sacrifice” just as Jesus sacrificed his life for our love and he redeemed our sins as he said: “There is no other love greater than sacrificing our life for others.” “S” or “Science” means “Knowledge,” which is the root of man’s ability to reason. Everyone should always aim at gaining more knowledge. The
5 SAINT GABRIEL’S COLLEGE, THAILAND more we learn about mundane knowledge, the more we should also learn about “Dharma” or religious, ethical virtues. Moreover, DIS also comes from the French phrase, “Dieu Seul,” which means “ALL WE DO IS FOR THE GRACE OF GOD ONLY.” It is to remind us of St. Louis Marie de Montfort, the Founding Father of the Brothers of St. Gabriel’s motto. With this powerful motto, we have the will to work without yielding to difficulties, at studies as well as at work. We all uphold it up to this day. A.M. and The White Lilies “A.M.” is abbreviated from a Latin word, “ALMA MATER,” meaning literally, “Dear Mother,” in Latin and indicating “MOTHER COLLEGE,” which symbolizes that our institution is like our “Alma Mater”, our own birth place and as a part of our own families. We should love our institution as much as we should love our own parents. Moreover, “A.M.” is also abbreviated from “AVE MARIA” (in Latin), the name of Jesus’ Mother. This means that we should love our own Mother with our heart and soul. And the beautiful snow - white lilies are symbols to remind us that we should be clean and sincere with all our thoughts, words and minds, wherever we are. The Star and The Man In a Boat “The Star and the Boat” symbolizes “Spiritual Hope” meaning that religion is “the light of Dharma or Absolute Truth” and all the knowledge or sciences we have learned from the institution is “the Light of the Intelligence”. Altogether they keep conduct and intelligence on track so we are not lost or capsized in the middle of the sea of life. “The man in the boat” reflects us, ourselves, rowing or guiding our own “boat of life”. “The Shield” That Frames The “Four Symbols” The “Shield” that frames the “Four Symbols” is the “COAT OF ARMS” which stands for “HONOUR,” or “PRIDE and DIGNITY”. It also represents the HONOUR, DIGNITY, PRIDE AND PRAISE that our institution has received from the King who reigns over the Kingdom.
